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.
