Characterization of viscoelastic properties of PDMS silicon rubbers

In this project we target a desired viscoelastic properties of PDMS for the application of thin wall membrane uses as a container to support soft test sample biomaterials during mechanical compression tests. The biocompatible PDMS membrane is produced by a ...

Chaotic mixing using source-sink microfluidic flows in a PDMS chip

Martinus Gijs, Abdeljalil Sayah, Caroline Vandevyver, Hüseyin Cumhur Tekin, Ata Tuna Ciftlik, Venkataragavalu Sivagnanam

We present an active fixed-volume mixer based on the creation of multiple source–sink microfluidic flows in a polydimethylsiloxane (PDMS) chip without the need of external or internal pumps. To do so, four different pressure-controlled actuation chambers a ...

Silicone substrate with in situ relief for stretchable thin-film transistors

Stéphanie Lacour

We have manufactured stretchable thin-film transistors and interconnects directly onto an engineered silicone matrix with localized and graded mechanical compliance. The fabrication only involves planar and standard processing. Brittle active device materi ...

Microchannel deformations due to solvent-induced PDMS swelling

François Gallaire

The compatibility of polydimethylsiloxane (PDMS) channels with certain solvents is a well known problem of soft lithography techniques, in particular when it leads to the swelling of the PDMS blocks. However, little is known about the modification of micro ...

Hyperelastic pressure sensing with a liquid-embedded elastomer

A hyperelastic pressure transducer is fabricated by embedding silicone rubber with microchannels of conductive liquid eutectic gallium-indium. Pressing the surface of the elastomer with pressures in the range of 0-100 kPa will deform the cross-section of u ...

Fast Organic Conditioning of Patterned Surfaces for Capillary Part-to-Substrate Self-Assembly

Massimo Mastrangeli

Selective chemical preconditioning of geometrically patterned substrates and parts is necessary to enable capillary part-to-substrate self-assembly. On the other hand, long preparation procedures may preclude the throughput enhancement potentially brought ...

Nanoporous SiN membranes patterned by wafer-scale nanosphere lithography

Jürgen Brugger, Andreea Veronica Savu, Oscar Vazquez Mena, Harry Heinzelmann, Mona Julia Katharina Klein, Raphaël Pugin, Franck Montagne

Nanoporous SiN membranes are interesting for a number of applications, e.g. stenciling, filtration, or tissue engineering [1-3]. The patterning of the pores requires a high resolution lithographic tool. Focused ion beam milling or e-beam lithography fulfil ...

The covalent attachment of adhesion molecules to silicone membranes for cell stretching applications

Jean-Jacques Meister, Hicham Majd, Boris Hinz, Lara Buscemi Estefanell, Pierre Jean Arnould Wipff

Strain devices with expandable polydimethylsiloxane (PDMS) culture membranes are frequently used to stretch cells in vitro, mimicking mechanically dynamic tissue environments. To immobilize cell-adhesive molecules to the otherwise non-adhesive PDMS substra ...

Nitric oxide release from Polydimethylsiloxane-based Polyurethanes

Evelyne Nguyen

In bypass graft surgery, surgeons have turned to synthetic materials such as polyethylene terephthalate (Dacron) and expanded polytetrafluoroethylene (ePTFE) when lacking sufficient and suitable arteries or veins for the procedure. However, due to their lo ...

Monolithic micro-direct methanol fuel cell in PDMS with microfluidic channel-integrated Nafion strip

Martinus Gijs, Meng Shen

We demonstrate a monolithic polymer electrolyte membrane fuel cell by integrating a narrow (200 mu m) Nafion strip in a molded polydimethylsiloxane (PDMS) structure. We propose two designs, based on two 200 mu m-wide and two 80 mu m-wide parallel microflui ...
