Thesis Ph. D. Michigan State University. Packaging 2015

Hemicellulose is the second most abundant component of plant cell walls after cellulose. It has received increasing interest as an alternative to petroleum based polymers for packaging applications because of its abundance, renewability and biodegradability. However, there are some challenges in the utilization of hemicellulose as a packaging material. Hemicelluloses are complex heteropolysaccharides with varied compositions and structures depending on the hemicellulose source (e.g., plant species, location and growth stage); they can also be influenced by the chemical, physical and biological isolation processes used to isolate them, and by any pretreatment used before isolation. It is critical to understand the influence of these factors (hemicellulose source, isolation approach, and pretreatment) on the final hemicellulose properties, such as mechanical and barrier properties, which are important for packaging applications. In addition, pure hemicellulose obtained from plants is water sensitive, brittle and weak, making it unsuitable for most packaging applications even though it is a good barrier for oxygen. Modification of hemicellulose is needed to meet the requirements of packaging materials such as protection against chemical, mechanical, physical and biological damage, and good barrier against water, oxygen, odors, etc.This research focuses on the fabrication and characterization of hemicellulose based films with adequate properties to enable their potential application as packaging materials. Three types of raw materials, aspen ChemiThermoMechanical Pulp (CTMP), spruce CTMP and hybrid poplar powder, with different pretreatments (bleaching and no bleaching) were employed to obtain hemicelluloses by an alkaline extraction method. The extracted hemicellulose was further formed into film by solvent casting in water with the addition of sorbitol and glutaraldehyde. These two chemicals were used as a plasticizer and a cross-linking agent, respectively, to improve the properties of hemicellulose films.Mechanical and barrier properties of the hemicellulose based films were determined. Hemicellulose sources and pretreatments played an important role in the properties of hemicellulose based films. Hemicellulose based films from less treatment (powder samples, no bleaching) displayed better properties than the films from more treatment (pulp samples, bleaching) in general. Hemicellulose based films prepared from hybrid poplar powder without bleaching exhibited the highest tensile strength (76.5 ± 7.0 MPa) and elongation at break (5.4 ± 0.9%), which were higher than the values obtained from other studies of similar hemicellulose based films. Glutaraldehyde was suggested to be responsible for this improvement. The modulus of elasticity (MOE) (3.5 ± 0.4 GPa) was comparable with those obtained for similar hemicellulose based films in other studies. The differences in molecular weight, lignin content and crystallinity for the hemicellulose film obtained from…

▼ Retort processing conditions of temperature, overpressure, and sterilization time were used to determine the impression depth on the pouch surface from contact with the retort rack during retort processing, also referred to as a waffling defect. Retortable flexible pouches were filled with 1,000 mL of water and processed in a horizontal water spray retort. A confocal laser scanning microscope was used to measure severity of the waffling defects. Data collected during this study showed that higher temperatures resulted in higher measured impression depth values (p<0.05) in all of the tested combinations. However, when the pouches were retorted at different temperatures, different effects of retort overpressure were observed. At a low temperature (111 deg. C), the higher overpressure resulted in higher severity of the waffling defects (p<0.05). In contrast, at a high temperature (131 deg. C), the higher overpressure resulted in lower severity of the waffling defects (p<0.05). When samples were retorted at different sterilization time settings, there was only one condition where a statistical difference in the impression depth values was observed (p<0.05). The longer sterilization time resulted in higher measured impression depth (p<0.05) only if the samples were retorted at a high temperature of 131 deg. C with a low overpressure of 26 psig. There was no statistical difference (p>0.05) in measured impression depth when samples were retorted at different sterilization time settings in other tested combinations. The difference in variance of the impression depth values between the samples retorted at different processing factor combinations was also studied. Processing factor combinations with a high temperature of 131 deg. C and a long sterilization time of 60 minutes, at any overpressure setting, resulted in a higher variance of waffling defect severity (p<0.05) compared to other combinations. The relationship between retort processing factors and waffling defect severity was explained using a prediction equation. The lack of fit of the proposed equation was not significant (p>0.05), while the hypothesis test (overall F-test) showed that the overall model was statistically significant (p<0.05). Therefore, the proposed equation is useful in predicting the average impression depth value when retort temperature, overpressure, and sterilization time are known. This study showed how retort processing factors affect the severity of waffling defects and proposed a method to predict the waffling defect severity. This information could allow pouch manufacturers to develop retortable pouches and food processors to create new retort processes to reduce waffling. Advisors/Committee Members: Dr. William S. Whiteside, Committee Chair, Dr. Ronald L. Thomas, Dr. Curtis H. Stowe.

▼ The abundance of biological low value sugar beet lignocellulose (SBL) after sugar extraction makes it a potential raw material for biodegradable flexible packaging films. This study attempts to develop a sustainable film from SBL with potential novel applications in packaging. Firstly, the dissertation investigated the effects of chemical pretreatments on the structure and properties of SBL. The study then is focused on improving SBL properties and demonstrating additional applications by developing flexible films with antimicrobial activity.The first objective involved a two-step pretreatment technology to improve the tensile, barrier, and thermal properties of SBL based films. Chemical analyses were used to identify and characterize sugar beet lignocellulose (SBL). Cellulose content of SBL was increased by sulfuric acid pretreatment and bleaching from 22.2% to 80.4%. This was attributed to removal of some lignin, pectin, and hemicelluloses as evidenced by non-destructive spectroscopic analysis. FT-IR spectroscopic analysis of fibers confirmed that the acid pretreatment led to partial removal of hemicelluloses and lignin from the structure of SBL. XRD results revealed that this acid pretreatment resulted in increased crystallinity of the SBL fibers. The thermal gravimetric analysis (TGA) was used to demonstrate the increased thermal stability after acid pretreatment due to the increased contribution of stable cellulose crystals. TGA curves after sulfuric acid pretreatment demonstrated a two-stage thermal degradation behavior due to the introduction of sulfated groups during the sulfuric acid hydrolysis process. These improvements after pretreatments are promising for the use of acid pretreated SBL as a source of bio-based lignocellulose to reinforce polymer composites and high value products from agricultural residues.In the second objective, composite films of pretreated SBL and polyvinyl alcohol (PVOH) plasticized with sorbitol were successfully developed. Film-forming dispersions of different ratios of SBL to PVOH (100/0, 75/25, 50/50, 25/75) were cast at room temperature. Films were evaluated for physical, tensile, water barrier, and thermal properties. The addition of PVOH gave significantly (P≤0.05) higher elongation at break (12.45%) and lower water vapor permeability (1.55 ×10^(-10) g s-1 m-1 Pa-1) than that of control. The ESEM results showed that the compatibility of SBL 50/PVOH 50 was better than those of other composite films. These results suggest that when taking all the studied variables into account, composite films formulated with 50% PVOH are most suitable for various packaging applications.In the third objective, SBL films were developed with cedarwood oil (CWO) and tung oil to improve the water barrier properties and antimicrobial activity. The microstructure of the composite films was characterized through Fourier transform infrared spectroscopy (FTIR). The results showed that cedar and tung oils can be used to decrease water vapor permeability of SBL films by more than 25%; the contact angle to… Advisors/Committee Members: Kamdem, Donatien Pascal, Selke, Susan, Matuana, Laurent, Chou, Karen.

Thesis M.S. Michigan State University. Packaging 2013.

This study was aimed at developing a single-step process that efficiently incorporates epoxidised soybean oil (ESO) into a poly (lactic acid) or PLA matrix in order to manufacture PLA sheet/film with improved flexibility without affecting other package characteristics. To achieve this goal, a processing system in which an extruder and a peristaltic injector pump attached in tandem was developed for a continuous and accurate incorporation of the plasticizer into the molten matrix.The effect of ESO addition levels on impact and tensile properties of plasticized PLA sheets was examined. The flexibility of plasticized specimens and the phase morphology between the plasticizer and the matrix were characterized through glass transition measurement and scanning electron microscopy, respectively. Additionally, this study examined the effect of plasticizer on the heat sealability of PLA film during pouch manufacture by measuring both the burst pressure and seal strength of the flexible pouches sealed at different sealing temperatures. Finally, the tensile properties of plasticized PLA blown films as a function of storage time over a span of 125 days was examined.The impact strength of plasticized sheets increased significantly with increasing ESO content, indicative of the toughening capacity of ESO as a plasticizer. The experimental results suggested approximately 15 wt % as the optimum concentration of ESO in plasticized sheet. The ductility of plasticized PLA sheets followed similar trends and the brittle-to-ductile transition occurred in the range of 5-10 wt % ESO content, in agreement with the impact strength results. In contrast, both the tensile strength and the modulus of the sheets decreased with increasing ESO content. This was expected due to the plasticization effect, which induced a decrease in the glass transition temperature resulting in mobility of the PLA polymer chains.Burst pressure and seal strength of PLA films were not affected by the addition of plasticizer or by the sealing temperature range studied. The tensile properties of blown film plasticized with 15 wt % ESO, tested at periodic intervals of storage time, indicated no significant change in the ductility and the tensile strength at yield as the storage time increased, implying the good permanence of ESO in the plasticized PLA films over a period of time tested. In contrast, the tensile modulus showed a slight but a statistically significant increase in stiffness after only 7 storage days, indicating a possible loss of plasticizer from the film as the storage time increased. This contradictory trend will be investigated further.

▼ Polymer-based multilayer nanocomposites have become favorable material choice for many applications such as gas barriers, water membranes, optoelectronic devices, biosensors, corrosion inhibitors and energy devices. They are finding their ways as a replacement of traditional metal, silicon oxides and hard inorganic coatings. The present work is dedicated to addressing the fabrication of new polymer flexible nanocomposites and their mechanical response against normal and lateral deformation modes, known as nanoindentation and nanoscratch. Particularly, the scratch resistance of these nanocomposites is critical for many applications. Little is known in the literature about their nanomechanics, hence reliability and durability for long-term applications. Better understanding of the nanomechanics and nanotribology of 2D multilayered thin films and 3D multilayered structures was achieved in this thesis through a series of different experiments using low and high load nanoindentation, nanoscratch and flat-punch compression. Complementary computational modeling supported the experimental findings and further explains their nano- and micromechanical behaviors. Based on the findings of these nanomechanical experiments, functional multilayered polymeric coatings consisting of different arrangements of polymers, graphene oxide and clay were found to be potential material choices for a range of different applications such as low-friction tribological coatings, vapor/gas barriers and self-healing coatings. Furthermore, 3D silicon/polymer structures specifically under extreme deformation were found to be a potential candidate for wearable electronics and flexible microelectromechanical systems (MEMS) sensors due to the resilient and elastic behavior driven by the geometry-dependent deformation of these structures. The last part discusses the development of a new material pertaining to the development of nanocomposites. On the quest of continuous search of 2D materials, which can act as reinforcements, a new material, Aluminum diboride (AlBv2) flakes, was introduced and discussed. High aspect ratio AlBv2 flakes is a potential reinforcement for conductive polymer nanocomposites due to the metallic conductivity in the axis parallel to the basal hexagonal plane. In summary, the findings above focused on the mechanics and tribology of nanocomposites at the nanoscale mainly for gas barrier applications and MEMS devices. However, the knowledge can also be extended to other devices such as energy harvesting devices and membranes where tribology issues at the nanoscale are of important concerns.

▼ Flexible packaging is a growing successful market and the majority of flexible package applications are for the food industry. The demand for process optimization and reduced production costs, has led to an increase in flexible packaging. However, fast production lines can result in contamination in the seal area. For flexible food packaging, contamination is considered any food particle or substance trapped in the seal area. Current quality control processes can detect contamination in the seal area, but it is not determined if seal contamination effects seal quality. Oil-based and sodium based snack foods are two common categories that can be packaged on a horizontal flow film and seal (HFFS) flow-wrap machine. The study uses vegetable oil and a salt water solution to simulate the effect of liquid contamination along the T-point of flexible pouches made on an HFFS. The T-point refers to where the fin seal meets the end seal and requires the seal jaw to seal through four layers of film, which is the most difficult point to seal. The study tests a combination of different sealing temperatures and dwell time to determine the optimal sealing condition for a hermetic seal. A quality hermetic seal provides an enclosed seal with no leaks due to successful polymer chain entanglement between the two sealant layers. The different test categories of the study are non-contaminated (control), salt water solution for salt based foods, and vegetable oil for oil-based foods. Given the test parameters of the study, 140⁰C sealing temperature and 0.3 seconds dwell time are considered to be the optimal sealing condition for all three test categories. For Phase 1 of the study, salt water has a lower hermeticity pass rate compared to vegetable oil and non-contaminated seals. In addition, the effect of refrigerated storage temperature and ambient storage temperature did not show to be significant for any of the test categories. However, refrigerated conditions showed a higher hermeticity pass rate, but it was not statistically different. The findings for seal strength indicated no test category had higher or lower seal strength over the 14 day test period. Overall, the study shows there is no effect of liquid contaminant on hermeticity and seal strength for flexible film with LLDPE sealant layer. Advisors/Committee Members: Dr. Kouhsik Saha.

Packaging is important not only in extending the shellife of fish and fishery products but also improving their marketability. In the recent years, significant development have taken place in the packaging industry. During the past decade in India, there is almost a packaging revolution with the availability of variety packaging materials, thus generating better packaging consciousness in other producer/manufacturing industries. But unfortunately, such realisation is not forthcoming in the fisheries sector and packaging techniques for local and export trade continues to be on traditional lines with their inherent drawbacks and limitations. Better packaging ensures improved quality and presentation of the products and ensures higher returns to the producer. Among several packaging materials used in fishery industry, ISI specifications had been formulated only for corrugated fibre board boxes for export of seafoods and froglegs. This standard was formulated before containersiation came into existance in the export of marine products. Before containerisation, the standards were stringent in view of the rough handling, transportation and storage. Two of the common defects reported in the master cartons exported from India are low mechanical strength and tendency to get wet. They are weakened by the deposits of moisture caused by temperature fluctuations during loading, unloading and other handling stages. It is necessary to rectify the above defects in packaging aquatic products and hence in the present study extensive investigations are carried out to find out the reasons for the damage of master cartons, to evolve code of practice for the packaging oi frozen shrimp for exports, development of alternative style of packaging for the shipping container, development of suitable consumer packaging materials for fish soup powder, cured dried mackeral, fish pickles in oil and frozen shrimp. For the development of suitable packaging materials, it is absolutely essential to know the properties of packaging materials, effect of different packaging materials on theirshelf life and their suitability for food contact applications.

As empresas estão se deparando com um mercado mais competitivo a cada dia, e em função desta realidade necessitam melhorar seus processos internos para agregar valor aos seus produtos e serviços e eliminar desperdícios para, desta forma, apresentar para o mercado maior qualidade e menor custo. Este trabalho tem como objetivo comparar a aplicação da melhoria contínua (kaizen) em duas empresas fabricantes de embalagens flexíveis e os resultados obtidos em cada uma delas em função da utilização ou não de um procedimento para a implementação. Numa empresa o procedimento utilizado foi o PDCA, suportado pelas ferramentas da qualidade em cada uma de suas etapas, enquanto que, na outra empresa, não foi aplicado procedimento algum e sim ações com base intuitiva não estruturada e com uma formatação definida pela própria empresa. Os resultados observados nas empresas objeto de estudo revelaram que a aplicação da melhoria contínua incrementa o desempenho das empresas, mas para o sucesso de sua implementação é fundamental que a condução seja baseada em procedimento consagrado para assegurar a sua eficácia.

Companies are facing a more competitive market each day, and in light of this reality need to improve their internal pocesses to add value to their products and services and to eliminate waste, thus presenting to market higher quality and lower cost. This study aims to compare the application of continuous improvement (kaizen) in two manufacturers of flexible packing and results in each depending on the use or absence of a procedure for implementation. In undertaking the procedure used was the PDCA, supported by the tools of quality in each of its stages, while in another company, the procedure was not applied, but some actions based on unstructured and intuitive with a format defined by the company. The result observed among in the companies under study, revealed that application of continuous improvement increases their performance but to the success of its implementation is essential that the conduct is based on established procedure to ensure their effectiveness.

A dissertação foi realizada em ambiente industrial, mais precisamente na empresa Monteiro, Ribas – Embalagens Flexíveis, S.A.. Esta empresa dedica-se à impressão e laminagem de filmes, assim como à confeção de sacos. Os seus produtos são direcionados na sua maioria para a indústria alimentar, exportando mais de 50% da sua produção, e dizem respeito a complexos (dois ou mais filmes unidos pela presença de um adesivo) que podem possuir impressão ou não. Estes complexos podem ser enviados para o cliente em bobina ou já em saco. Os objetivos propostos pela empresa diziam respeito a estudos relacionados com a força de laminagem dos complexos, com o coeficiente de atrito dos mesmos e com a identificação dos espetros dos componentes dos adesivos, assim como o estudo do processo de reticulação dos mesmos por espetrofotometria de Infravermelho. Relativamente aos resultados obtidos verificou-se que tanto a tinta como os metalizados influenciam negativamente a força de laminagem. Por sua vez o coeficiente de atrito é afetado por vários fatores. Através dos ensaios experimentais verificou-se que o adesivo, a tinta e o verniz mate favorecem o aumento do valor do COF. Além disso, nos complexos em que se utilizaram filmes de polietileno de maior espessura obtiveram-se valores de COF mais baixos, e no que diz respeito à temperatura e à tensão de enrolamento, verificou-se que valores mais elevados e muito baixos da primeira traduzem-se num aumento do valor do COF e uma tensão de enrolamento maior também tem o mesmo efeito. Relativamente ao tipo de filme impresso, substratos com maior energia superficial atraem mais o agente de deslizamento (slip). Por último, não se conseguiu perceber qual o tipo de adesivo (com ou sem solvente) que tem maior impacto no COF uma vez que em 55% dos casos o valor do COF é superior nas amostras que foram complexadas com adesivo sem solvente e em 45% o COF era superior nas amostras complexadas com adesivo base solvente. No que diz respeito aos espetros obtidos verificou-se que a reticulação dos adesivos é identificada pela diminuição da extensão do pico correspondente à ligação N=C=O.

The dissertation was carried out in an industrial environment, specifically the company Monteiro, Ribas - Flexible Packaging SA. This company is dedicated to printing and laminating films as well as the confection bags. Its products are targeted mostly for the food industry, exporting over 50% of its production, and involve complexes (two or more films together by the presence of an adhesive) that have printing or not. These complexes can be sent to the customer in coil or already in bag. The objectives proposed by the company concerned studies of the lamination strength on the complexes, the coefficient of friction of them and the identification of the spectra of the components of the adhesives as well as the study of the crosslinking process thereof. In what concerning the results they show that the ink and metallic coat harm the lamination of the complexes. In turn, the coefficient of friction is affected by different…

System in a package (SIP) allows integrated circuit (ICs) modules or other components from different suppliers and technologies to be integrated into highly functional products. This SIP could realize miniaturized and multifunctional systems enabling emerging technologies like solid-state lightening (SSL), internet of things (IOT), etc. Due to the limitations of wire bond ,flip chip and RDL’s on high topography devices, Self-aligned Wafer Level Integration Technology (SAWLIT) based on PDMS has been reported by H. Sharifi in 2007 [1]. In this thesis a novel polymer-based SAWLIT and processing details are presented. Polyimide was chosen to be the flexible substrate for interconnects due to its high bending stiffness, high thermal and chemical stability, low dielectric constant and high mechanical strength. Two prototypes, down-contact and up-contact, have been developed for packaging with embedded cavities. Down-contact prototype utilizes isotropic plasma etching to create cavities underneath the interconnects. A plasma isotropic under etch study was carried out. The study includes the horizontal and vertical etch rates versus etch time and mask width. In up-contact prototype, flexible interconnects were initially fabricated on a sacrificial layer, then transferred to the device wafer with the help of temporary wafer bonding techniques and conductive glue. For the up-contact devices, prototypes were fabricated. Both liquid polyimide precursor and Kapton® film were used to produce polyimide flexible substrates with transferrable interconnect. Metal sheet resistance of such transferred interconnect were calculated and measured after transfer to evaluate the feasibility. These prototypes illustrate the potential of transferable interconnects to shorten the process time and to reduce cost.

▼ As pragas de produtos armazenados constituem um problema para o homem, depreciando produtos e causando prejuízos econômicos. Dentre estas pragas temos o Lasioderma serricorne (F. 1792), Sitophilus zeamais (M. 1855) e Plodia interpunctella (H. 1813) conhecidos por infestar produtos armazenados como: grãos, farelos, farinhas, café, fumo, frutas secas e especiarias. Essas pragas perfuram e adentram as embalagens, ovipositando sobre o substrato. Neste contexto a embalagem desempenha um papel fundamental, impedindo o contato e proliferação de pragas no produto acondicionado. Assim, para proteger o produto acondicionado e prolongar a sua vidaútil a embalagem deve apresentar boa resistência mecânica à tração e à perfuração, boa selabilidade, boas propriedades de barreira e não transferir odores nem sabores estranhos ao produto acondicionado. A radiação ionizante pode causar mudanças estruturais nos materiais poliméricos de embalagens, essas mudanças são causadas pelos processos de cisão e reticulação das cadeias poliméricas. Estes são processos concorrentes e a predominância de um sobre o outro depende da estrutura química do polímero, das condições da irradiação e de fatores específicos do material que irá absorver a energia. Este trabalho teve o objetivo de avaliar as mudanças nas propriedades mecânicas de estruturas de embalagem utilizadas para armazenar granola, barra de cereais e macarrão, bem como suas resistências a perfuração por L. serricorne, P. interpunctella e S. zeamais, quando submetidas a radiação por feixe de elétrons. Na metodologia foram utilizadas cinco estruturas de embalagem comercialmente utilizadas para armazenar granola, barra de cereais e macarrão compostas por (Polipropileno bi-orientado metalizado/Polipropileno bi-orientado coextrusado - BOPPmet/BOPP 50 μm), (Polipropileno bi-orientado/Polipropileno - BOPP/PP 50 μm), Poli(tereftalato de etileno) metalizado/Polipropileno bi-orientado coextrusado - PETmet/BOPP 32 μm), Poli(tereftalato de etileno)/Polipropileno - PET/PP1 72 μm) e Poli(tereftalato de etileno)/Polipropileno - PET/PP2 32 μm). As estruturas de embalagens foram submetidas à doses de radiação entre 0, 10, 20 e 60 kGy, em um acelerador de elétrons de 1,5 MeV, 25 mA e 37,5 kW, à taxa de dose de 11,22 kGy/s, temperatura ambiente e presença de ar. Oito dias, 2 meses e 6 meses após as irradiações foram realizados ensaios mecânicos de resistência a tração e elongação na ruptura, resistência da selagem e resistência à perfuração, todos com base nas suas respectivas normas ASTM [35]. Os ensaios de perfuração por insetos foram realizados em sala climatizada, onde amostras irradiadas nas doses de 0, 10, 20 e 60 kGy foram seladas contendo 40 g de granola, 40 g de macarrão e barra de cereais em número de nove por ensaio, e divididas igualmente em três caixas plásticas teladas por dose estudada. Em cada caixa foram adicionados 20 adultos de cada inseto em por 60 dias, quando as embalagens foram avaliadas para verificação de possíveis perfurações. As diferenças entre os resultados das… Advisors/Committee Members: Arthur, Valter.

Les travaux de thèse portent sur le développement de méthodologies d'élaboration de dispositifs à base de polymères PDMS, destinés à des applications médicales. Ce travail s'appuie sur deux volets applicatifs : le développement de matrices de micro-capteurs capacitifs souples portables destinées à la mesure de champs de pression dans un contexte de suivi d'appuis du corps humain, et le développement d'une technique de collage réversible de composants PDMS dans une application de laboratoire sur puce en micro-fluidique. Dans ces travaux, les propriétés mécaniques du PDMS sont déterminées expérimentalement et à l'aide de modélisations numériques, afin d'identifier les éléments essentiels du dimensionnement des micro-capteurs capacitifs. Différents types de micro-capteurs de pression souples sont réalisés par un procédé de microfabrication à transfert de films. Ce procédé est optimisé à chacune de ses étapes afin d'obtenir un procédé fiable et reproductible. Les caractérisations électromécaniques montrent que les capteurs fabriqués sont opérationnels et adaptés aux applications médicales visées. Les capteurs de pression normale ont une variation de capacité de 3 à 17 % à 10 N - 300 kPa, adaptée à une application dentaire. Les capteurs à trois axes de sensibilité ont une résolution spatiale de 25 mm2, et une sensibilité de 4 % à 3 N en compression et 1,4 % par Newton en cisaillement pur, et sont adaptés à une application de mesure de la pression plantaire destinée à l'analyse de la marche et la détection des hyper-appuis. Par ailleurs, deux méthodes différentes permettant le collage réversible de composants PDMS sont développées. Les dispositifs microfluidiques fabriqués avec ces méthodes peuvent être utilisés avec jusqu'à 5 cycles de collage/décollage, et travailler à débit élevé (500 µL/min, correspondant à une pression de 148 kPa). Les méthodologies développées dans ces travaux ouvrent la voie à l'élaboration de dispositifs à base de PDMS performants et optimisés pour répondre à des cahiers des charges exigeants pour des applications biomédicales ciblées.

This thesis focuses on the development of methodologies dedicated to the development of PDMS-based devices, which are required in medical applications. Two objective applications are considered in this work: i) the development of wearable flexible micro-sensors arrays for measuring pressure fields on human body and ii) the development of a reversible bonding technique of PDMS components dedicated to microfluidic chips. In this work, the mechanical properties of PDMS are determined using experiments and computations; they allow identifying the essential elements of the design of capacitive micro-sensors. The manufacturing process is reliable and reproducible, and different types of flexible pressure sensor have been fabricated by a film transfer process. Electromechanical characterizations show that the fabricated sensors are fully operational and suitable for the intended applications. Normal pressure sensors have a capacitance change ranging from 3 to 17% under a…

▼ Novel engineered materials have drawn considerable interest as they provide new opportunities for future antenna miniaturization and RF packaging. This dissertation is dedicated to the development and application of the novel polymer-ceramic composites for future compact multilayer antennas and RF systems. The first half of the dissertation focuses on polymer-ceramic composites to achieve a new class of material with superior mechanical (light-weight, flexible and load-bearing) and electric (high permittivity, low loss) properties. Carbon nanotube (CNT) sheets are introduced for the first time to overcome the issues of reliable printing on polymers. Compared with single CNTs, the proposed CNT sheets achieve high conductivity for antennas and RF applications. Concurrently they exhibit strong adhesion to the polymer surface, making them attractive as a smart skin for future small unmanned areal vehicles (UAVs) and body-worn applications. The second half of the dissertation focuses on the application of the polymer-ceramic composites with carbon nanotube sheet printing. Two practical application examples are elaborated, namely (1) a compact anti-jamming GPS array and (2) a cylindrically conformal microstrip array. For these applications, the polymer-based dual-layer GPS antenna is used to demonstrate the suitability of polymer-ceramic composites for multilayer antenna configurations. The pre-cure liquid form of the polymer-ceramic composites and low temperature processing are highly desirable properties for three-dimensional (3-D) fabrication and multilayer packaging. Also, the cylindrically conformal microstrip array demonstrates the application of the polymer-ceramic composites for flexible electronics due to their high flexibility, controllable permittivity and low loss. Overall, this dissertation demonstrates for the first time that polymer-CNT materials are well suited for light-weight, conformal, multi-functional antenna and RF systems.

Ce travail consiste à développer un système convertissant une partie de l’énergie mécanique du cœur en électricité pour alimenter les stimulateurs cardiaques de nouvelle génération, implants sans sonde ni batteries implantés directement dans la cavité cardiaque. Après études de différentes sources d’énergies et concept associés, l’option liée à la pression sanguine, appliquant sur une partie souple du boîtier de l’implant des efforts transmis à un transducteur interne les convertissant en électricité, s’est révélée la plus prometteuse. Cette solution présente les avantages principaux suivants par rapport aux systèmes inertiels usuels : grande densité de puissance, adaptabilité au rythme cardiaque et potentiel de miniaturisation. Un boîtier ultra-souple électro-déposé de 10 µm d’épaisseur en forme de soufflet a été modélisé, fabriqué et caractérisé, validant ainsi le concept de récupérateur proposé. Un transducteur électrostatique novateur (3D multicouche à peignes interdigités et à chevauchement hors-plan), étudié par des modélisations analytiques et numériques, est en cours de fabrication. Selon l’électronique associée, ce transducteur promet une grande densité d’énergie extraite. Un transducteur piézoélectrique micro-usiné en forme de spirale et à électrodes micro-structurées, est également présenté. Les défis spécifiques des spirales dontla flexibilité permet d’augmenter l’énergie mécanique d’entrée sont étudiés notamment par simulation numériques, et des prototypes ont été micro-fabriqués et caractérisés. Au final, une énergie de 3 µJ/cm3/cycle est obtenue et de nombreuses perspectives d’amélioration permettent d’envisager une puissance au moins 10 fois supérieure.

This work consists in the development and design of an energy harvesting device to supply power to the new generation pacemakers, miniaturized leadless implants without battery placed directly in heart chambers. After analyzing different mechanical energy sources in the cardiac environment and associated energy harvesting mechanisms, a concept based on regular blood pressure variation stood out: an implant with a flexible packaging that transmits blood forces to an internal transducer. Advantages compared to traditional inertial scavengers are mainly: greater power density, adaptability to heartbeat frequency changes and miniaturization potential. Ultra-flexible 10-µm thin metal bellows have been designed, fabricated and tested. These prototypes acting as implant packaging that deforms under blood pressure actuation have validated the proposed harvesting concept. A new type of electrostatic transducer (3D multi-layer out-of-plane overlap structure with interdigitated combs) has been introduced and fully analyzed. Promising numerical results and associated fabrication processes are presented. Also, large stroke optimized piezoelectric spiral transducers including their complex electrodes patterns have been studied through a design analysis, numerical simulations, prototype fabrication and experimental testing. Apower density of 3 µJ/cm3/cycle has…
