| Abstract(in English) | We are developing the pulse-frequency-modulation (PFM) retinal prosthesis vision chip for the purpose of the visual sensation by electrical stimulus to the retinal cells. We have designed and fabricated a 16x16-pixel PFM vision chip as a retinal prosthesis device. This vision chip is a prototype for demonstrating application in in vitro electrophysiological experiments. Each pixel has a bonding pad on which a stimulus electrode is formed by Pt/Au stacked biocompatible electrode. We have evaluated the vision chip by in vitro electrophysiological experiments using detached frog retina, and confirmed that it can electrically stimulate the retinal cells effectively. |
