Stimulus performance of poly-Si thin-film transistor in in-vitro experiment for artificial retinas

Abstract

We are developing artificial retinas using poly-Si thin-film transistors (TFTs), which is suitable for the epiretinal implant on the curved human eyeballs. In this study, we confirmed stimulus performance of poly-Si TFTs in in-vitro experiment for artificial retinas. It is found that correct output waveforms are observed using a CMOS inverter and ring oscillator. This means the stimulus performance of the poly-Si TFTs is sufficient for arftificial retinas.
