Biological Stimulation Performance of LTPS-TFTs Artificial Retina by Wireless Power Drive

Artificial retinas are biological stimulation devices aiming at visual regeneration by stimulating retinas of blind patients. We have developed an artificial retina using low temperature poly silicon thin film transistors (LTPS-TFTs) driven by wireless power transfer. The artificial retina can be installed on a patient's retina and obtain power by wireless power transfer from the coil embedded in the glasses. In this study, we have succeeded in confirming the operation of the artificial retina by wireless power transfer in phosphate buffered saline (PBS).
