| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we developed photo sensors using illuminance dependence of current-voltage characteristics of pin Thin-Film Photo-Transistors (TFPT) and the detection circuits by poly-Si TFTs, and applied them to artificial retinas. We clarified the relationship between the voltage of the analog voltage output photosensors and illuminance as well as the relationship between the frequency of the frequency output photosensors and illuminance. We also confirmed them in the artificial retinas. Furthermore, we produced an eyeball model to examine the dynamic performance and succeeded in capturing the ON / OFF and movement of the light source as moving images. Moreover, we were able to recognize not only a simple circular shape of the light source but also text "T" and "C" by retinal prosthesis. Finally, we found that we can convert AC power to DC power wirelessly, and succeeded in recognizing the shape of light source of 800 [Lx] which was close to actual environment light. | |
