Abstract :
A CMOS-based multi-chip flexible retinal stimulator with light-sensing function was designed. The light sensing function is implemented for light-controlled retinal stimulation in subretinal configuration. The basic functionality and feasibility of the multi-chip flexible retinal stimulator was confirmed. A photo-activating operation with adjustable photosensitivity was successfully implemented on the retinal stimulator without any additional input line. We demonstrated and characterized the photosensing function.
