Abstract
Common retinal degenerative disorders such as retinitis pigmentosa and age-related macular degeneration cause irreversible loss of vision. Retinal prosthetic devices replace the retinal photoreceptor functions by producing electrical stimulation for inducing visual perception artificially. However, recent retinal prostheses have achieved very limited success in regaining vision?achieving only up to a few dozens of pixelized phosphenes. This project pursues a fully integrated nano-engineered retinal prosthesis that completely departs from the status quo with a path forward to restore natural, high-resolution vision in the affected population. The engineering effort pertains the design and development of high-performance light-sensitive electrode arrays, as well as innovation in the wireless interface, communication, stimulation waveform generation, system control, and biocompatible packaging and surgical assembly. Preliminary in vitro experiments show restored light responsivity through the nano-engineered implant, as a stepping stone to further developments towards in vivo validation and clinical trials.
