Stretchable Electrodes for Neuroprosthetic Interfaces

Stéphanie Lacour, Nicolas Vachicouras, Ivan Rusev Minev, Katherine Marie Musick, Anna Cyganowski

We have developed a stretchable gold microelectrode array (MEA) that can withstand the torsion requirements needed for implantable neuroprosthetic interface applications. The array is composed of thin gold (sub-100 nm thick) electrodes on a soft, 120 mu m ...

Photopatterning the mechanical properties of polydimethylsiloxane films

Stéphanie Lacour

Silicone rubber films with graded and localized mechanical properties are prepared using two-part polydimethylsiloxane (PDMS) elastomer, photoinhibitor compounds and conventional photolithography. First the un-cross-linked PDMS is mixed with benzophenone. ...

New/Surface-Modified Biocompatible Polymer for ICD Lead Insulation

Rubin Berek Pisarek

The average lifetime of an implanted pacemaker or defibrillator cable (lead) is approximately 10 years. One of the main lead failure mechanisms is deterioration of the insulation, which can be caused by chemical, biological, and mechanical processes. Each ...

Norland optical adhesive (NOA81) microchannels with adjustable wetting behavior and high chemical resistance against a range of mid-infrared-transparent organic solvents

Nico de Rooij, Philip Wägli

Different methods to adjust the wetting behavior of surfaces of the UV-curable adhesive NOA81 were investigated and quantitatively characterized by dynamic contact angle measurements with an optical goniometer. A new method to make NOA81 surfaces hydrophob ...
