TFA and coating procedure. (a) TFA measured 27.8 mm × 0.4 mm × 20 μm () with 20 functional platinum sites (180 μm diameter, 250 μm pitch). Two 16-channel Omnetics connectors bonded to the backend of each array enable signal transfer. (b) Topside application of silicone adhesive. (c) Final silicone coated TFA (cTFA). Note silicone ball at distal tip to reduce the potential for insertion trauma.
