a Two different designs for the active strips were realized (blue box). The ground contact site was split to 109 circular redundant connected contacts with a single diameter of 80 µm (red box). b The layer setup of both designs was chosen identical. c In the assembled TIME implant a surgical needle with a suture was incorporated within the thin-film loop (TIME-4H). The polyimide-based thin-film electrode was attached via the MFI technique to an interconnecting by use of screen-printing structured ceramic. To this in turn 16 helically wound MP35N- wires covered by a medical-grade silicone rubber hose were soldered and terminated on the opposite side in a commercial connector. Colored silicone rubber and an identification tag made of laser-structured platinum were used for distinct identification.
