Schematic illustration of the subretinal implant. The implant is composed of an SU-8 substrate and is designed as a 1 mm circular device constructed of 1,020 micro-wells (20 µm in both diameter and height) with a gold electrode at the bottom for neural activation. a) Top view of a complete implant structure. b) Side view, SU-8 micro-well-like structures; height 17 µm with the gold electrode at the bottom
