Outline
Text
We present a retinal stimulator with a light-controlled function for subretinal implantation. The stimulator is based on a multiple-microchip architecture which has previously been developed to realize over 1000 stimulus electrodes by our group. The retinal stimulator can be controlled by the intensity of light through the light-controlled function embedded in each microchip. The fabricated stimulator was implanted in a rabbit eye and stimulated retinal cells. The EEP signals were successfully obtained.
