Recent advances in micro fabrication technology have resulted in proliferation of microscale mechanical devices, most of which are applied in the biomedical field and clinical diagnostics. One of the most promising technology platform is microflow cytometry, which requires biological cells to be focused in single file and presented in front of a detection system. The heart of a microflow cytometer is the generation of a sample stream with a diameter of the order of the particles to be measured. In order to be successfully analysed and to reduce measurement errors, particles should be focused in all three dimensions. Limitation in fabrication capability at reduced scales has resulted in adapting the macroscopic approach to a more simplified planar one. In recent years, a number of three dimensional flow focusing devices have been documented, but the "perfect" system still has to come. The primary objective of this research thesis is to demonstrate that a microdevice for 3D hydrodynamic focusing can be fabricated at a dimension achievable from cost effective CNC manufacture. In order to do so, two devices of same design but different scale have been fabricated. CFD and confocal experiments demonstrated the ability of the proposed design to fully control size and dimension of the focused stream. The sample stream diameter were ten to twenty times smaller than the channel dimensions. Horizontal and vertical hydrodynamic focusing can be obtained independently and the flow remains stable until Re=30, which is six times higher than the appropriate operating condition of previously presented devices. The injection of microbeads proved that a stable cells/particles line-up can be achieved with 90% efficiency. The proposed device was also successfully employed with biological cells. A simple approximation of the theoretical model to predict the size of the focused stream is also presented. An automated fluorescence-based optical counting technique was integrated with the system and evaluated using two different cell lines. This method compares favorably to the Trypan blue exclusion assay and to the visual count of the cells from the digital picture. In order to further improve the efficiency of the technique, the proposed device was employed to vertically focus the cells in a narrow region in the centre of the channel and therefore reduce fluorescence variability. Cell aggregation and sedimentation into the cell dispensing apparatus was reduced without reducing cell viability by developing a novel magnetic stirrer

▼ On April 20th 2010, the largest offshore oil spill in U.S. history happened in the Gulf of Mexico. It is estimated total more than 4 million barrels oil spilled to Gulf of Mexico. More than two million gallons had been used. This had made the threat to coastal and sea ecosystem even greater and long term. Real-time monitoring is also a critical topic for oil spill response. In-situ monitoring devices are needed for rapid collection of real-time data. A new generation of instruments for spilled oil detection is reported in this paper. The main hypothesis in this research is that the sensitivity of the new instrument based on a micro-fluidic-optic chip can be higher than its conventional sized counterparts. The adoption of the micro-fluidic-optic chip helped to miniaturize the sample extraction unit and also to integrate the optical detection on the same chip substrate. Only the monitoring and displaying unit and the power supply were external to the micro-fluidic-optic chip. In this way, the micro-fluidic-optic chip is replaceable and can be disposable. This also helps to eliminate the need for cleaning the fluidic components, which may be very difficult in micro-scales because of surface tension and flow resistances. Liquid-Liquid extraction unit for sample pre-concentration and micro-optic components for fluorescence detection are the key microfluidic components and have been designed and fabricated on a single disposable chip. In the Liquid-Liquid extraction system, different designs are compared and electromagnetically actuated micro-valves and peristaltic pumps have been designed and fabricated to control the aqueous sample fluid and the organic phase solution. In the micro-optic detection system, different designs are compared and an out-of-plane lens was designed, fabricated, and integrated to enhance the measurement sensitivity. The experimental results of the integrated system have proved that the liquid-liquid extraction functioned very well and the overall measurement sensitivity of the system has been increased more than six hundred percent. An overall oil detection sensitivity blow 1ppm has been achieved. The research work presented in this dissertation has proved the feasibility of this novel oil detection instrument based on micro-fluidic-optic chip. This detection system may also be used for detection of other samples that can be measured based on fluoresce principles.

▼ A MEMS based electrostatic field sensor is presented which uses capacitive interrogation of an electrostatic force deflected microstructure. First the deflection of the sensor’s membrane which is caused by electrostatic force in the presence of electric field is calculated both by simulation and theoretical model and it has been shown that the results of the simulations have acceptable values compared to the theoretical ones. Simulation models have also been designed to improve the vibration of the membrane for measuring the ac electric fields. It has been shown that by adding perforations to the surface of the membrane, it is possible to reduce the air drag force effect on the membrane and still have similar electrostatic force on the membrane. Therefore, it is possible to reduce the damping due to air resistance in membrane movement when measuring ac fields. After successful modeling of the sensor structure, the fabrication process for the sensor has been designed. The electroplating process as the most important fabrication step has been studied in detail prior to starting the fabrication of sensor. The process parameters for electroplating process, such as current amplitudes, duty cycle and frequency have been optimized to get the lowest surface roughness to thickness ratio for the electroplated films. A lithography molding process was developed for the electroplating. Both dc and pulse plated films have been studied to show the role of pulse plating in improving the quality of the electroplated films. It was found during the release process that the electroplated copper interacted with sulfur during plasma etching of silicon. However, the result of the releasing process was very helpful to find the best recipe of releasing and they can be used in next projects.

Ce travail de thèse porte sur le développement technologique d’outils miniaturisés micro- (10 µm) et milli- (1 mm) fluidique, pour l’étude in situ de procédés de filtration frontale, en collaboration avec l’entreprise Solvay. Les outils développés permettent le suivi visuel de la formation de gâteaux de filtration en opérant des essais à pression ou à débit constant sur diverses suspensions colloïdales, jusqu’à des pressions trans-membranaires de l’ordre de 7 bars.L’étude millifluidique de la filtration de dispersions industrielles de silice colloïdale (Solvay, Silica), a permis de mettre en évidence la croissance de gâteaux compressibles et de corréler ces données aux signaux de pression, obtenus à débit imposé. Ces mêmes données sont confrontées aux lois classiques de la filtration (« cake filtration theory »), mettant en évidence que les modélisations classiques ne peuvent pas reproduire les comportements observés.La seconde partie de la thèse porte sur le développement d’un outil microfluidique, intégrant des membranes hydrogel nano-poreuses, pouvant résister à de fortes pressions (quelques bars). Ces membranes sont fabriquées in-situ par photo-polymérisation de formulations aqueuses contenant des PEG-diacrylates et des agents porogènes. Notre travail a permis une caractérisation précise de leur perméabilité en fonction de divers paramètres (formulation, temps d’exposition, géométrie). Ces mêmes membranes ont été utilisées pour suivre la filtration frontale de nanoparticules aux échelles microfluidiques, et ainsi estimer quantitativement la perméabilité des gâteaux formés.

This work deals with the technological development of miniaturized micro- (10 µm) and milli- (1 mm) fluidic tools for in-situ investigations of frontal filtration processes, in collaboration with Solvay. The tools that we developed, make it possible to monitor visually the formation of the filter cake, operating at constant-pressure or constant-flow rate filtration, on various colloidal suspensions, and up to trans-membrane pressures of 7 bars.We performed a millifluidic study of the filtration of industrial silica colloidal dispersions (Solvay, Silica), and we evidenced the growth of compressible cakes. We correlated these data to the pressure signals obtained at imposed flow rates. The comparison with theoretical predictions given by the classical laws of cake filtration theory, shows that such conventional models cannot reproduce the observed behaviors.The second part of this thesis reports the development of high pressure-resistive (several bars) microfluidic tools integrating nano-porous hydrogel-based membranes. These membranes are fabricated in situ by photo-polymerization of aqueous formulations containing PEG-diacrylates and porogen agents. We reported precise characterizations of their permeability in function of several parameters (formulation, exposure time, geometry). The same membranes were used to monitor frontal filtration of nanoparticles at the microfluidic scale, and thus to quantitatively estimate the permeability of the…

Depuis ces dernières années, il y a eu augmentation de l’effort pour le développement des systèmes microfluidiques dédiésà la dispersion d’une phase fluide dans une autre phase fluide immiscible. Les gouttelettes ou les bulles résultantes ont de nombreuses applications dans des diverses domaines (photonique, chimique, biologique...). Pour la plupart de ces applications, il est primordial de contrôler la taille et la forme de ces gouttelettes/bulles, paramètres qui influencent directement le comportement ou la réponse du système. Notre but consiste ainsi à générer des gouttelettes de taille unique (mono-dispersées) et contrôlable pour produire des structures accordables. Nous analysons aussi leurs mécanismes de formation et étudions les paramètres qui influent sur leur taille et leur forme. Dans le présent travail, la génération de gouttelettes est réalisée en utilisant une intersection entre deux microcanaux (jonction en T) où leur taille est directement liée à la géométrie. Dans cette configuration, il existe trois régimes connus de génération de gouttelettes qui sont les régimes de dripping, squeezing et jetting. Nous nous sommes particulièrement intéressés à l’étude du régime dripping car il assure la génération de gouttelettes ayant une taille plus petite que celle obtenue avec les autres régimes. Les expériences et les études théoriques ont montré que le diamètre des gouttelettes diminue quand la largeur des canaux diminue, quand la vitesse de la phase continue augmente et quand la vitesse de la phase dispersée diminue. De plus, nous avons pu mettre en évidence un nouveau régime de génération de gouttelettes pour lequel les gouttelettes générées ont un diamètre constant, indépendamment des vitesses des phases continue et dispersée, et qui ne dépend que de la géométrie des canaux. Nous avons appelé ce nouveau régime le régime “balloon”. Nous avons enfin montré l’intérêt de l’accordabilité des systèmes microfluidiques en optique et en acoustique. Ainsi, nous avons montré que la période du réseau de diffraction optique est facilement modifiable en contrôlant les paramètres de génération de bulles. De même, nous avons pu voir que la réponse acoustique est liée `a la résonance des bulles dans le milieu liquide. Cette réponse est une fonction du diamètre des bulles générées. Enfin, nous proposons l’utilisation du système microfluidique en électronique pour produire des capacités variables, ouvrant la voie à des nouvelles fonctionnalités pour la microfluidique diphasique.

Since the past few years, there has been an increasing effort in developing microfluidic devices for dispersing one fluid phase in another immiscible fluid phase. Micro fluidic bubbles or droplets have many applications in different fields such as photonics, chemistry, biology... For most of these applications, it is important to control the size and the shape of these droplets or bubbles, since they directly influence the response of the system. Our goal is to generate mono disperse and controllable droplets to produce tunable structures. We also…

▼ Ce travail examine l'influence de plusieurs technologies émergentes, telles que l'imprimante 3D (I3D), et les plateformes de manufacture en ligne (PML), sur les modèles d'affaires et les dynamiques de fabrication. À cette fin, cette recherche est divisée en trois chapitres. Le premier chapitre traite de la manière dont l'I3D mène au développement de nouveaux modèles d'affaires. Les conclusions d'une étude de cas multiples montrent que l'I3D peut non seulement influencer la création de valeur et la proposition de valeur des entreprises ; cela peut également influer la communication et la distribution de valeur dans une plus grande mesure que celle rapportée dans les études précédentes. Selon les personnes interrogées, les I3D encouragent la création de nouveaux modèles d'affaires et impactent également les entreprises existantes. L'I3D permet la création de nouveaux services et produits. Le deuxième chapitre explore le modèle des micro-usines (MU), les éléments qui le permettent et ses implications sur les économies d'échelle et de gamme. Après avoir examiné des sources secondaires en ligne, nous affirmons que la grande polyvalence et les niveaux d'automatisation de certaines MU peuvent leur permettre de combler l'écart entre les processus de production artisanale et de masse, d'accroître l'innovation et de faciliter la fabrication locale à la demande de produits personnalisés. Le troisième chapitre identifie, classe et compare plusieurs MU et PML. Les résultats d'une étude de cas multiples et de « recherche expérientielle » suggèrent deux dimensions principales qui différencient les MU : l'automatisation et l'ouverture. Nous développons une taxonomie des MU basée sur ces dimensions. MU avec une automatisation relativement faible et des niveaux d'ouverture élevés, MU avec une automatisation élevée et des niveaux d'ouverture faibles, et MU avec une automatisation relativement faible et des niveaux d'ouverture faibles. Il existe deux types de PML, les plateformes fermées, qui optimisent les installations et équipements industriels des grands fabricants, et les plateformes multifaces, qui connectent des clients avec des fabricants indépendants. Les PML multifaces peuvent être bas de gamme ou haut de gamme, en dépendant des marchés ciblés. _____________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : imprimante 3D, fabrication additive, modèles d'affaires, micro-usines, économies d'échelle et de gamme, fabrication numérique, fabrication à la demande locale, plateformes de manufacture en ligne, études de cas, recherche expérientielle

Pour résoudre la limitation inhérente au procédé d’impression laser LIFT, une approche utilisant une double impulsion (DP-LIFT) a été développée au cours de cette thèse. Dans ce processus, une irradiation laser de durée de quelques dizaines de microsecondes crée un bain de métal en fusion et une seconde impulsion ultra-brève induit le mouvement du fluide, la formation d’un jet ou d’une goutte et le transfert du métal liquide. Cette thèse présente une étude expérimentale détaillée sur le processus DP-LIFT. L'influence des paramètres des deux irradiations laser a été étudiée en s’appyuant sur un ensemble de méthodes d'observation. Pour étudier l’influence de ces paramètres sur la dynamique de l’éjection, un modèle basé sur la conservation de l’énergie a été utilisé. De plus, nous avons démontré que, pour certaines configurations des diamètres respectifs des deux spots lasers, des nanojets focalisés étaient générés. Enfin, en conservant une épaisseur ﬁxe du film métallique, des gouttelettes uniques, sans débris, d'un diamètre allant de 670 nm à 6,0 µm ont été imprimées avec une reproductibilité élevée. des matrices de piliers ont également été imprimées pour démontrer le potentiel de la méthode LIFT à double impulsion pour la fabrication de micro-structures 3D

To solve the inherent limitation of Laser-induced Forward Transfer (LIFT), a double pulse LIFT (DP-LIFT) approach has been developed in this thesis. In this process, a ﬁrst long pulse laser irradiation creates a melted metal pool and a second ultrashort pulse induces the ﬂuid motion and initiates the jetting transfer. This thesis provides a detailed experimental study on the DP-LIFT process. The inﬂuence of double pulse parameters on the jetting phenomena has been carefully studied by means of various observation methods. To predict the jetting behaviors, an energy balanced model has been used. Moreover, we demonstrated that for some conﬁgurations of the respective diameters of the two lasers, focused nanojets are generated from the melting pool. Finally, from a ﬁxed thickness of the donor ﬁlm, debris-free single droplets with diameters ranging from 670 nm to 6.0 µm have been printed with high reproducibility. 2.5 D pillars matrix are printed to demonstrate the potential of the double pulse LIFT method for the fabrication of 3D micro-structures.

Ce travail de thèse présente la conception et la réalisation d’un capteur de pression 3D flexible pouvant être intégré dans un gant ou sur un outil de chirurgie pour qualifier et quantifier les forces de préhension notamment sous contraintes normales et de cisaillement. Un état de l’art présente d’abord les technologies se prêtant à cette application. Puis, le choix est porté sur la conception et le dimensionnement à partir de la loi de Hooke, d’un capteur matriciel capacitif tri-axe de 8 x 8 x 3 cellules/cm² à partir d’un diélectrique flexible de faible module d’Young autour de 1 MPa. Les cellules conçues ont une capacité nominale voisine de 0,5 pF. Une variation de 30% est attendue à une force maximale envisagée de 100 N/cm². La dynamique visée est de 1 à 1000. Elle correspondant à une résolution de 0,15 fF ou 100 mN/cm². La fabrication du capteur souple est abordée en prenant en compte la caractérisation des matériaux support, notamment le Kapton, dans un flux de microfabrication. Les problèmes de métallisation et d’adhérence d’électrodes sur PDMS conduisent au développement d’un procédé basé sur la technologie de transfert de film adapté aux électrodes enfouies dans le PDMS. Des résultats de simulation sous ANSYS valident le principe physique exploité. Ils sont confirmés par des mesures électriques statiques et en charge du capteur tactile pour des forces de 10 mN à 20 N.

This PhD work presents the design and realization of a 3D flexible force sensor that can be integrated in surgical gloves or tools to qualify and quantify the grip forces including normal and shear stress. A state of the art first presents the suitable technologies for this application. Then, the choice is focused on the design and dimensioning, using Hooke’s law, of a capacitive tri-axis sensor of 8 x 8 x 3 cells/cm² matrix from a flexible dielectric of low Young’s modulus around 1 MPa. Designed cells have a nearby nominal capacitance of 0.5 pF. A variation of 30% is expected at maximum force range of 100 N/cm². The aimed dynamic is 1 to 1000. It corresponds to a resolution of 0.15 fF or 100 mN/cm². The flexible sensor fabrication is tackled by taking into account the characterization of support materials, notably the Kapton, in a stream of microfabrication. Metallization and adhesion of electrodes on PDMS problems lead to the development of a process based on film transfer technology adapted to electrodes buried in PDMS. On the basis of ANSYS simulations, the operating physical principle is validated. They are confirmed by static and in charge electrical measurements of the tactile sensor for forces ranging from 10 mN to 20 N.

Les travaux de cette thèse ont porté sur la conception et la réalisation d'un dispositif d'éclairage surfacique à géométrie planaire à base de structures plasmoniques, pour un fonctionnement à 633nm. Ce dispositif sera capable de convertir une lumière incidente cohérente en un faisceau de sortie uniforme sur la surface du dispositif, collimaté et avec un angle prédéfini par rapport au plan du dispositif. Pour réaliser ce dispositif, la solution envisagée est l'utilisation d'un réseau de guides d'onde diélectriques pour répartir la lumière sur la surface, et de chaînes de nano-structures d'argent couplées aux guides, dimensionnées comme des antennes pour réémettre la lumière hors du plan.Les travaux réalisés ont mis en évidence le contrôle du couplage entre le guide d'onde et la chaine de nano-structures d'argent, modulable par plusieurs paramètres dans une gamme comprise entre 10% et 90 % : nombre de particules, dimensions des particules, distance entre le guide et les particules. En jouant sur la période de la chaine, il est possible d'obtenir un rayonnement hors-plan, avec un angle déterminé par la formule des réseaux de diffraction. Des émetteurs élémentaires, composés d’un guide et de chaines de particules, ont été fabriquées en salle blanche et caractérisés sur un banc d’optique guidée à l'aide d'un montage de projection dans le plan de Fourier. Les diagrammes de rayonnement expérimentaux sont en accord avec les simulations. De premiers résultats ont également confirmé expérimentalement la possibilité de moduler le couplage guide-chaine en modifiant les dimensions des particules. Enfin le réseau de guides d'onde a été dimensionné pour une surface d'1 cm² et fabriqué en lithographie par projection. Les pertes linéiques mesurées dans les guides d'onde sont de l'ordre de 5 dB/mm. Plusieurs optimisations peuvent être réalisées pour améliorer la qualité des guides. A partir des données expérimentales obtenues et des simulations de propagation de faisceau, une configuration réaliste de dispositif d’éclairage incluant le nombre et le positionnement des émetteurs sur le réseau de guides a été proposée. L’ensemble des travaux réalisés valident l’approche choisie.

This work has focused on the design and realization of a planar lighting device based on plasmonic structures, for a 633nm operation. This device will be able to convert a coherent incident light into a uniform output beam over the surface of the device, collimated and with a predefined angle with respect to the plane of the device. To achieve this feature, the proposed solution is the use of an array of dielectric waveguides to distribute the light over the surface, and silver nanostructures chains coupled to the waveguides and dimensioned as antennas to retransmit the light out of the plane. The work carried out has highlighted the control of the coupling between the waveguide and the silver nanostructures chain, modulated by several parameters in a range between 10% and 90%: the number of particles, particle size, distance between the guide and the…

D’après les données de l’agence International de Prévention de la Cécité, 253 millions de personnes souffrent de pathologies visuelles dans le monde. Il existe des pathologies affectant les photorécepteurs de la rétine causant des millions de déficients visuels sans traitement efficace disponible. Les implants rétiniens ont déjà montré sa capacité pour stimuler de façon électrique les cellules rémanentes de la rétine grâce à un réseau de micro-électrodes de façon à obtenir une réponse neuronale puis une perception visuelle. Ces travaux de thèse en lien avec les implants rétiniens porteront sur deux aspects principaux concernant de nouvelles configurations de micro-électrodes et une analyse comparative des matériaux constitutifs des électrodes avec des tests en vieillissement long terme. Pour le premier aspect, de nouvelles géométries d’électrodes ont été développées en différentes phases : en commencent par une modélisation par éléments finis de la micro-électrode, suivi par la micro fabrication des prototypes et les expériences in-vivo. Pour l’étude du vieillissement des matériaux constitutifs des micro-électrodes, un banc de caractérisation a été développé pour reproduire les conditions de pH, T et stimulation électrique d’un implant réel. Le banc nous permet aussi d’étudier l’évolution de façon comparative des caractéristiques des différents matériaux grâce à la mesure de son impédance électrochimique

Regarding to data provided by the International Agency for Prevention of Blindness, 253 million people suffer some kind of visual impairment around the world. There is a group of diseases that affect the photoreceptors causing millions of impairment cases around the world that do not have an efficacious treatment. Retinal prostheses have proved to electrically stimulate the remaining cells of the retina by means of implantable microelectrode arrays to elicit their response and therefore visual perception. This PhD work tries to study two aspects of these devices: first, new electrode geometries that stimulate the cells in a more efficient manner; and second, the ageing of the different material used for the fabrication of the microelectrodes. For the first aspect new electrode geometries have been developed based on the state of the art. This development has been divided in different phases beginning with a FEM modeling of the electrode, followed by the microfabrication of the structures and their test in-vivo. In order to study the ageing of the microelectrode materials, a characterization bench that reproduces the conditions that an implant has to face during its implantation has been developed. This bench allows us to study in a comparative manner the evolution of the characteristics of the different materials thanks to the measurement of their electrochemical impedance

L’étude proposée est une étude préliminaire en vue d’utiliser des microrésonateurs en silicium fonctionnalisé en vue de la détection électromécanique d’espèces biologiques présentes à l’état de trace. Deux aspects ont été principalement étudiés : la capture ultra-sensible mais aussi la capture ultra-spécifique d’espèces biologiques comme des marqueurs pour la maladie d’Alzheimer. Elle a été effectuée dans le cadre d’une collaboration entre le département MINASYS (Micro et Nano-Système) de l’Institut d’Electronique Fondamental (IEF) et le Laboratoire Protéines et Nanotechnologies en Sciences Séparatives de la Faculté de Pharmacie de Châtenay-Malabry.Il s’est ainsi s’agit de développer un micro-résonateur en silicium intégrant des canaux enterrés permettant la circulation d’un fluide biologique à l’intérieur de la poutre et non à l’extérieur comme ils le sont plus couramment, et ce, dans le but de limiter au maximum l’amortissement du résonateur. En ce qui concerne les aspects en biologie, nous nous sommes plus particulièrement interessé à la détection d’un bio-marqueur de la maladie d’Alzheimer, le peptide amyloïde Aβ1-42. Jusqu’à présent, le dépistage de la maladie nécessite une concentration suffisamment importante de bio-marqueurs et le recours à une ponction du liquide céphalorachidien après l’apparition des symptômes de la maladie est donc nécessaire. Le microsystème présenté ici permettra de nous approcher d’un système capable de détecter des traces de biomarqueurs présentes dans le sang ou l’urine par exemple. Ainsi, dans un premier temps, nous avons mis au point un mode de détection précoce du peptide Aβ1-42 couplant un canal micro-fluidique et la microscopie à fluorescence. La surface des canaux en silicium doit être fonctionnalisée afin de permettre le greffage spécifique des antigènes. Pour cela, nous avons mis au point une technique s’appuyant sur la reconnaissance spécifique anticorps-antigène, celle-ci nécessitant une étape préalable de fonctionnalisation chimique de surface.Le manuscrit présenté ici s’articule en quatre parties principales. Dans un premier temps, une étude bibliographique permet de faire l’état de l’art sur le principe de fonctionnement de différents types bio-capteurs couramment utilisés et leurs performances. Une seconde partie décrit la fonctionnalisation de surface du silicium et plus spécifiquement de la réaction de silanisation en phase liquide réalisée sur des surfaces planes et dans des canaux fluidique. Nous abordons ensuite le domaine de la reconnaissance spécifique d’entités biologiques et détaillons les étapes de greffage des protéines réalisées sur les surfaces ainsi que la conception d’immuno-sandwich entreprise dans des canaux fluidiques. Enfin la dernière partie du manuscrit rassemble des différents résultats préliminaires obtenus en vue de l’élaboration du micro-capteur de type poutre résonante à canaux enterrés.

This study is a preliminary study to use a fonctionnalized microsensor based on electromechanical detection of biological species present at trace levels.…

▼ Electrodeposition is one of the main techniques for fabricating conductive parts with one or two dimensions in the micron size range. This technique is utilized to coat surfaces with protective films of several micrometers thickness or fabricate standalone microstructures. In this process, an electrochemical reaction occurs on the electrode surface by applying an electric voltage, called overpotential. Different electrochemical practices were presented in the literature to obtain kinetic parameters of an electrochemical reaction but most of these practices are hard to implement for the reactions occur on a microelectrode. Toward addressing this issue, the first part of the dissertation work presents a combined experimental and analytical method which can more appropriately provides for the kinetic measurement on a microelectrode. Another issue which occurs for electrodeposition on microscale recessed areas is the deviation of the profile of the deposition front from the substrate shape. Non-uniform deposition front usually obtains for a deposit evolved from a flat substrate with microscale size. Consequently, a subsequent precision grinding process is required to level the surface of the electrodeposited microparts. In order to remove the need for this subsequent process, in the second and third parts of the dissertation work, multiphysics modeling was used to study the effects of the fabrication parameters on the uniformity of the deposit surface and suggest a design strategy. Surface texture of the deposit is another parameter which depends on the fabrication parameters. Several important characteristics of the electrodeposited coating including its wettability depend on the surface texture. The next part of the dissertation work presents an experimental investigation and a theoretical explanation for the effects of the overpotential and bath concentration on the surface texture of the copper deposit. As a result of this investigation, a novel two-step electrodeposition technique is developed to fabricate a superhydrophobic copper coating. In the last part of the dissertation work, similar investigation to the previous sections was presented for the effects of the fabrication parameters on the crystalline structure of the deposit. This investigation shows that nanocrystalline and superplastic materials can be fabricated by electrodeposition if appropriate fabrication parameters are applied.

▼ Biopsy is a standard practice in the diagnosis and treatment of many cancers. Despite its integral role in cancer diagnosis, in some instances, the biopsy tool facilitates metastasis by transferring cancerous cells attached to its exterior into the healthy tissue or the blood circulation during its retraction from the tumor. These few cancer cells can then serve as seeds for the malignant tumor to grow in the healthy tissue. Cauterization using extreme heat or cold can destroy cells in the region and minimize the chance of seeding but this can be an inexact process that increases damage to otherwise healthy tissue and prolongs healing time following a biopsy procedure. In our laboratory, we have developed the concept of a new smart biopsy tool that can reduce the chance of cancer cell dissemination during a biopsy. This tool improves on the conventional biopsy needle by introducing an impedance sensor on the biopsy tool which is housed in a sliding sheath. Due to the significant difference in the electrical conductivity of the tumor and the healthy tissue, the sensor is able to distinguish between the two and locate the exact tumor interface. The protective sheath placed around the instrumented biopsy tool and above the interface isolates the healthy tissue and prevents or at least minimizes the transfer of tumor cells. Delivering an RF dose through the sheath can kill any malignant cells that might be lurking around the interface. This thesis, in particular, will concentrate on the development of the design, fabrication and calibration of the impedance sensor and its integration with the biopsy tool. The impedance sensor essentially consists of conductive electrodes sandwiched between insulating layers. They are built on thin-film polymer, Polyimide, using conventional microfabrication techniques. These sensors are further calibrated to estimate the cell constant. Once calibrated, these probes are used to measure the conductivity of porcine tissues, and in-house prepared agar phantoms. Advisors/Committee Members: Mahajan, Roop L.

▼ The vision of this PhD research project is to create a microfluidic system for controlling the locations of suspended particles in order to form three dimensional (3D) objects on demand. To realize this, the author implemented a microfluidic system that can apply suitable and desired forces on particles on demand. Particles of various refractive indices were placed close to each other in order to form a media having reconfigurable and tuneable properties. Light was coupled into such well-controlled particles in order to form dynamically tuned objects suspended in liquid such as optical waveguides. The dielectrophoretic (DEP) force was used for manipulating the locations of particles as it is capable of focusing and scattering suspended particles from pre-determined locations. Additionally, when combined with hydrodynamic forces, the DEP force was able to form densely packed areas of such particles with non-turbulent boundaries. The research was implemented in three stages. In the first stage, the author utilized a platform consisting of a microfluidic system integrated with DEP microelectrodes, microfluidics and optical peripherals for the coupling of light. Light was directly coupled into densely packed silicon dioxide (SiO2) particles with diameters of 230 and 450 nm, respectively. Light was transmitted via the closely packed 230 nm particles and in contrast was significantly scattered by the 450 nm particles. The outcomes, which were resulted from this initial stage, were the first demonstration of a dynamically tuneable optical waveguide based on the DEP focused particles in microfluidics. In the second stage of his research, the author integrated a multi mode polymeric waveguide into the microfluidic system. Tungsten trioxide (WO3) and SiO2 particles with diameters of 80 and 450 nm were investigated. The findings demonstrated that the densely packed WO3 particles were able to couple light from the polymeric waveguide, while the SiO2 particles did not affect the transmission of the optical signals significantly. The investigations of the second stage platform resulted in the first demonstration of optical waveguide tuning based on DEP focused particles. Finally, in the third stage of this research, the author implemented a quasi single mode polymeric waveguide integrated with the microfluidics. The author used WO3, zinc oxide (ZnO) and SiO2 particles with diameters of 80, 50 and 72 nm, respectively. Under the DEP force, these particles were able to interact with the optical guided modes. The results show that the WO3 particles were capable of forming layers of packed particles with anti-resonant characteristics. In particular, the fundamental mode was strongly coupled to the packed WO3 particles. However, under certain particle focusing conditions, the first order mode was anti-resonant to the closely packed WO3 particles as it was largely isolated. These findings were the first demonstration of the coupling and manipulation of optical guided modes using DEP focused particles with resonant and anti-resonant…

▼ Microtubules are cytoskeletal filaments that self-assemble from αβ tubulin dimers and are essential for cellular mechanics, cell division and intracellular cargo transport. Carrying out these functions requires numerous accessory proteins that bind to and interact with microtubules. The study of microtubules and microtubule associated proteins (MAPs) is relevant for understanding aging, developing cancer therapies, and providing approaches to treating neurodegenerative diseases. This thesis is devoted to using bioengineering tools and biophysical reconstitution methods to elucidate molecular mechanisms by which MAPs carry out their functional roles in mitosis, in organizing the neural cytoskeleton, and other processes. The mitotic motor kinesin-5 is best known as a homotetramer, however, motor properties independent of its homotetrameric configuration are not well understood. From in vitro assays, an engineered kinesin-5 dimer was found to stabilize microtubules by slowing GMPCPP microtubule depolymerization and promote dynamic microtubule growth by inhibiting catastrophe. Single-molecule experiments showed that kinesin-5 remains associated with microtubule plus-ends for a duration of 7 seconds. These results demonstrate that in addition to its role in sliding apart antiparallel microtubules, kinesin-5 is a microtubule stabilizer, polymerase and end-tracker. To maintain microtubule uniformity in dendrites of Drosophila neurons, microtubules growing into branches need to be guided towards the cell body. To investigate the mechanism of microtubule guidance, purified EB1 and kinesin-2 were dimerized to form an EB1-kinesin complex, and this complex was shown to be sufficient to steer the growth of one microtubule towards plus-end of another microtubule, providing a mechanism for maintaining uniform microtubule orientation, not only in neurons but also in other cells. Also, this work demonstrates that the dynamic EB1-microtubule interaction is sufficiently strong to carry out mechanical functions in cells. In vitro reconstitution can be used to investigate microtubules and MAPs in well-defined environments, but it is usually limited to single microtubules. To eliminate this constraint, micro-patterned electrodes were fabricated on elevated pedestals and high frequency AC fields were used to align microtubules on the opposite electrodes, thus forming a bipolar artificial mitosis spindle in 3D with microtubule plus-ends oriented towards the overlap zone. These aligned microtubules provide a platform for investigating MAPs in a spindle-like geometry. Cellulose synthase complex (CSC) is a membrane bound multi-subunit complex that synthesizes cellulose microfibrils and has great meaning in plant cell morphologies and commercial applications. To estimate the copy number and stoichiometry of CSC in a nondestructive way, GFP-CESA3 in Arabidopsis was photobleached under total internal reflection (TIRF) microscopy. A step detection algorithm was developed and the smooth bleaching traces were analyzed by to identify discrete… Advisors/Committee Members: William O Hancock, Dissertation Advisor/Co-Advisor, William O Hancock, Committee Chair/Co-Chair, Melissa Rolls, Committee Member, Christopher Martin Yengo, Committee Member, Richard Cyr, Committee Member, Thomas Nelson Jackson, Committee Member.

▼ Contact-Aided Compliant Cellular Mechanisms (C3M) are compliant cellular structures with integrated contact mechanisms. The focus of the thesis is on the design, fabrication, and testing of C3M structures with curved walls for high strain applications. Global strain capability is increased in these compliant mechanisms by replacing straight walls with curved walls in the traditional honeycomb cellular structure. The addition of contact mechanisms also increases cell performance via stress relief. Furthermore, curved walls are beneficial for fabrication at the meso-scale. The curved honeycomb unit cell, defined by a set of variables, is analyzed using finite element analysis. Each unit cell is subjected to an input displacement that is incremented up until the maximum local strain is equal to the allowable strain. The effective maximum global strain of the cell is then calculated from the input displacement. For each cell the non-contact global strain (maximum global strain in a cell without a contact mechanism) and the contact-aided global strain (maximum global strain in a cell with a contact mechanism) are calculated. For the contact-aided cells the ideal contact gap must also be calculated. It was found that curved C3M structures are always capable of larger global strains than straight-walled structures. Analysis of various cell geometries, reveals that the best cells have curved walls, are tall and slender, and do not benefit from a contact mechanism. Two optimization problems were formulated using MATLAB and finite element analysis to find the best non-contact and contact-aided cells. The first problem optimizes global strain in contact-aided cells, where the value of the objective function is found by taking the product of the contact-aided global strain and the increase in global strain that can be obtained due to stress relief. The second problem optimizes global strain in the non-contact cells, where this objective function is equal to the non-contact global strain. The optimized solutions for the curved cells can achieve global strains of up to 32.4% in non-contact cells and 19.7% in contact-aided cells. The lost mold rapid infiltration forming (LM-RIF) microfabrication process was used to fabricate C3M structures from both metallic (mesoscale 316L Stainless Steel) and ceramic (3mol% yttria stabilized zirconia) materials. The LM-RIF process is utilized to directly fabricate structures from CAD models in multiple arrays of C3M parts. After the parts are fabricated, they are tested experimentally using a custom test rig. During testing, a micrometer drives the displacement of the C3M mechanism, and the corresponding force is recorded via a built in force gauge. The displacement and force are both recorded through a computer interfaced to the system. This data gathered from the test rig is verified by calculating the displacements using digital images. Three different types of C3M specimen are tested and the force versus displacement data corresponds to predicted data with Moduli of… Advisors/Committee Members: Mary I Frecker, Thesis Advisor/Co-Advisor, Mary I Frecker, Thesis Advisor/Co-Advisor.

▼ The ever decreasing power consumption in electronic devices and sensors have facilitated the development of autonomous wireless sensor nodes (WSNs), which ushered in the era of the Internet of Things (IoT). However, the problem of long-term power supply to the numerous WSNs pervasively dispersed to enable the IoT is yet to be resolved. This work focuses on the development of novel vibration energy harvesting (VEH) devices and technologies for effective transduction of mostly wide-band and noisy ambient mechanical vibrations to power WSNs. In this thesis meso-scale and MEMS-scale nonlinear and frequency tunable VEH devices have been designed, fabricated and characterized. The first meso-scale VEH prototype developed in this thesis combines a nonlinear bistable oscillator with mechanical impact induced nonlinearity, which exhibits upto 118% broadening in the frequency response over a standalone bistable system. The second meso-scale prototype combines magnetic repulsion induced bistable nonlinearity with stretching induced monostable cubic nonlinearity in a single device structure. The device effectively merged the beneficial features of the individual nonlinear bistable and monostable systems, and demonstrates upto 85% enhanced spectral performance compared to the bistable device. The third prototype is a MEMS-scale device fabricated using spiral silicon spring structure and double-layer planar micro-coils. A magnetic repulsion induced frequency tuning mechanism was incorporated in the prototype, and it was demonstrated that both linear and nonlinear hysteretic frequency responses could be tuned (by upto 18.6%) to match various ambient vibration frequencies. In order to enhance the power generating capability of MEMS-scale electromagnetic devices, an ultra-dense multi-layer micro-coil architecture has been developed. The proposed ultra-dense micro-coil is designed to incorporate double number of turns within the same volume as a conventional micro-coil, and significantly enhance the magnetic flux linkage gradient resulting in higher power output (~4 times). However, attempts to fabricate the ultra-dense coil have not been successful due to lack of proper insulation between the successive coil layers. Finally, a power management system combining diode equivalent low voltage drop (DELVD) circuit and a boost regulator module was developed. It was demonstrated that energy harvested from harmonic and bandlimited random vibrations using linear, nonlinear bistable, and combined nonlinear VEH devices could be conditioned into usable electricity by the power management system with 60% - 75% efficiency. In addition to developing new prototypes and techniques, this thesis recommends directions towards future research for further improvement in vibration energy harvesting devices and technologies.

▼ Silicon photonics has emerged as a disruptive technology to address the exponentially growing demand for bandwidth in optical interconnects and data communications. The silicon material system supports large wafers, high device yield and performance uniformity, leveraging the half-century of investment by the electronics industry. Silicon is transparent in the 1.3 - 1.6 µm wavelength range, and has higher refractive index than its oxide, enabling submicron waveguides. On the other hand, the high index contrast between silicon and oxide, 3.4 to 1.4, making silicon photonic devices very sensitive to geometry variations commonly seen in complementary metal-oxide-semiconductor (CMOS) fabrication. I demonstrate a design approach using coupled particle swarm optimization (PSO) and finite difference time domain (FDTD) method that produces highly compact, efficient and robust passive devices. Silicon also has a high thermo-optic coefficient, 1.8×10-4 K-1, making resonant devices, which are critical for wavelength filtering and multiplexing, sensitive to temperature perturbations that are common in practical environments. A universal stabilization approach based on bandgap temperature sensor and active feedback control is presented. In addition to passive devices, active device such as modulators, photodetectors, and lasers are needed for practical photonics integrated circuits (PICs). Electro-optic modulation in silicon can be achieved by free carrier plasma effect, typically implemented as reverse biased p-n junction overlapping with the waveguide mode. However lasing or photo detection is inherently not available in silicon, and is only possible by integrating other optically active materials. Germanium is the preferred absorber because of its CMOS compatibility, but germanium processing has received far less attention than silicon so far, with active ongoing research trying to understand its implantation, dopant diffusion, and metal contact alloying properties. Hence a photodetector that does not require doping or metallization of germanium is highly desirable. I propose and demonstrate a germanium-on-silicon photodetector using only intrinsic germanium and no metal-germanium contact, which significantly simplify the process flow. The detector shows 1.14 A/W responsivity, over 40 GHz 3 dB bandwidth, and less than 1 µA dark current.
