Thin films and microelectrode arrays for neuroprosthetics
- Juan Ordonez, Martin Schuettler, Christian Boehler, Tim Boretius and Thomas Stieglitz
- Discussion of adhesion & ideas of using siliconcarbides as opposed to adhesion promoters (Silane A-174) to maintain good metal-polymer adhesion even with an equilibrium water vapor pressure.
- Transition metals form carbide bonds with polyimide, but noble metals do not.
- A one-metal (preferably noble) system is advantageous, as two metals will form a galvanic cell and eventually corrode.
- Therefore it's best to develop non-metallic non-toxic adhesion promotion technologies.
