Abstract:
The energy supply for the stimulation arrays is the key component in retinal implants. Usually, the thin film solar cell is used to supply energy, but it can not supply enough stimulation power. One of the general idea of incident energy supply is radio frequency (RF) circuit. Another method is to convert near infrared (NIR) radiation and enable retina cell stimulation. In this paper, firstly, we aim at listing these two energy supply methods, and introduce the characteristics of RF circuit and NIR conversion method. Especially, we present the design procedure in detail. The next part is a discussion on the advantage and disadvantage of adopting these two methods. At last, we explicate the new research and application of the energy supply for the use as retinal implants, and we envisage the future.
