Abstract

The electrical cochlear implants (Cls) have given > 500,000 patients worldwide a better life to date. However, the electrical neural stimulation has limited spatial resolution due to the spread of stimulation current, which reduces the number of effective channels to < 10 and results in a restricted perception of sound. Recently developed CIs such as optogenetic Cls have overcome this limitation, enabling much higher effective channel count [1]. However, such CIs require much larger power consumption (>100mW) and a higher data transmission rate (>lMb/s) than conventional Cls. As a result, designing a simultaneous wireless power and data transfer (SWPDT) system becomes challenging. AIso, due to the short distance between transmitter (TX) and receiver (RX) coils separated only by a scalp, frequency splitting may occur, and it should be carefully considered.
