Abstract
Optoelectronic retinal prostheses transduce light into electrical current for neural stimulation. A novel optoelectronic pixel architecture is presented comprising a vertically integrated photo junction field-effect-transistor (Photo-JFET) and neural stimulating electrode. Experimental measurements demonstrate that optically addressed Photo-JFET pixels utilize phototransistive gain to produce a broad range of neural stimulation current and can effectively stimulate retinal neurons in vitro. The compact nature of the Photo-JFET pixel can enable high resolution retinal prostheses with a theoretical visual acuity ˜20/60 to help restore vision in patients with degenerative retinal diseases.
