Wireless power supply to artificial retina using poly-Si thin-film transistor

摘要

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 have evaluated the wireless power supply to the artificial retinas using poly-Si TFTs. From simulation, it is found that the transmission efficiency can be 0.43 % currently. This value should be improved but acceptable because our artificial retina consumes very low power.
