摘要

A subretinal prosthetic device includes a substrate provided under a retina, a return electrode for receiving a current such that a ground is formed on the substrate, a plurality of stimulating electrodes provided on the substrate and for generating an active potential to an optic nerve in response to external visual information projected onto the retina, and a switch for controlling the current between each of the plurality of stimulating electrodes and the return electrode. The switch is connected between the plurality of stimulating electrodes and the return electrode to ground the plurality of stimulating electrodes to the return electrode in response to an on or off control signal.
