Shape memory polymers with controlled time-dependent shape recovery

The aim of this thesis has been to investigate the use of heat-activated shape memory polymers (SMPs) as novel smart actuators for the controlled delivery of fluids and their suitability for applications such as low-cost drug delivery. On heating to temper ...

Fabrication of structured anode-supported solid oxide fuel cell by powder injection molding

Jan Van Herle, Antonin Faes, Zacharie Wuillemin, Amédée Zryd

Powder Injection Molding (PIM) gives the possibility to produce, at an industrial rate, ceramic parts with fine details. It is thus a possible approach to reduce the fabrication costs of Solid Oxide Fuel Cells (SOFCs). This work presents fabrication and el ...

Polymer micro-molding of femtosecond laser micromachined substrates

Yves Bellouard

Micro-molding can be used for the cost-effective fabrication of elements such as active or passive components in MEMS devices, hydrophobic surfaces, cell-growth scaffolds or optical components such micro-lens arrays and gratings. This method is also partic ...

Investigation of process-induced strains development by fibre Bragg grating sensors in resin transfer moulded composites

Véronique Michaud

A comprehensive understanding of the development of residual strains in composite processing is essential to manufacture high quality composite parts. In this paper, the use of fibre Bragg grating (FBG) optical sensors was investigated to measure in situ t ...

All-optical switching in an optofluidic polydimethylsiloxane: Liquid crystal grating defined by cast-molding

Demetri Psaltis, Andreas Vasdekis, Julien Cuennet, Luciano De Sio

We report an optofluidic photoswitchable grating, based on a polydimethylsiloxane periodic structure on a glass substrate, separated by a thin liquid crystal film. The polydimethylsiloxane microstructure was realized via high resolution replica molding and ...

Seismic Behavior of Shell-to-Base Connections in Large Storage Tanks

Alain Nussbaumer, Gustavo Cortes

A study of non-anchored tanks found in Switzerland (Koller, 2003) revealed that the plastic rotation of the shell-to-bottom connection in four of the six tanks studied did not satisfy the 0.2 radians limit established by the Eurocode (Eurocode-8, 2005). Th ...

0-level Vacuum Packaging RT Process for MEMS Resonators

Mihai Adrian Ionescu, Cyrille Hibert, Daniel Grogg, Nicolas Abelé

A new Room Temperature (RT) 0-level vacuum package is demonstrated in this work, using amorphous silicon (aSi) as sacrificial layer and SiO2 as structural layer. The process is compatible with most of MEMS resonators and Resonant Suspended-Gate MOSFET [1] ...

Stiffness degradation and life prediction of adhesively- bonded joints for fiber-reinforced polymer composites

Thomas Keller, Anastasios Vassilopoulos, Ye Zhang

Adhesively-bonded joints, including double- and stepped- lap joints (DLJs and SLJs), were experimentally investigated under cyclic tensile loading. The joints were composed of pultruded GFRP laminates and epoxy adhesive. A critical stiffness was found for ...

Development of pressure sensors by powder technology

Peter Ryser, Sebastien Martinerie, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot

Thick film deposition of conductive, dielectric and resistive pastes on ceramic membranes is a cost effective technique to manufacture piezoresistive pressure sensors. Thick-film resistors consist of a percolating network of conductive oxide nanoparticles ...

Void Formation And Transport During SMC Manufacturing: Effect Of The Glass Fibre Sizing

Véronique Michaud, Emmanuelle Comte

The present study investigates the origin of voids in sheet molding compounds (SMCs) sheets and their transport during the manufacturing steps. Paste mixing, impregnation, thickening, and molding have been performed with five different SMC sheets, one with ...
