Abstract

The retinal prosthesis test device is comprised of a thin wafer of glass made from nanochannel glass (NGC) with very small channels perpendicular to the plane of the wafer filled with an electrical conductor forming microwires. One surface of the glass is ground to a spherical shape consistent with the radius of curvature of the inside of the retina. The NGC is hybridized to a silicon de-multiplexer (30) and a video image is serially input to a narrow, flexible micro-cable (27) and read into a 2-D array of unit cells in a pixel-by-pixel manner which samples the analog video input and stores the value as a charge on a MOS capacitor. After all unit cells have been loaded with the pixelvalue for the current frame, a biphasic pulse is sent to each unit cell which modulates the pulse in proportion to the pixel value stored therein.
