Details of aGC neural probe. (a) 15-channel aGC ECoG probe, (b) In inset: Magnified SEM image of a single microelectrode in the ECoG probe. Also, FIB cross-section of the GC microelectrode taken at the edge between GC and Durimide is shown revealing a seamless integration of the layers. (c) Expanded view of FIB cross-section taken at a GC wire trace leading to one of the microelectrodes, (d) High-resolution (50,000×) FIB image of a cross-section taken through a GC wire trace. Box in bottom of (a) shows the location where FIB through GC interconnect was taken. Note that there are no adhesion layers or metal layers in aGC probes.
