Artificial vision

Solar cells for the blind

Article metrics

Electronic implants have been used to restore visual function lost as a result of retinal degeneration. Combining subretinal high-pixel-density arrays with optically powered serial photovoltaic sensors may alleviate some of the difficulties associated with today's devices, which rely on implanted arrays and inductive coils.
