Safety Ensuring Retinal Prosthesis With Precise Charge Balance and Low Power …

Abstract—Ensuring safe operation of stimulators is the most important issue in neural stimulation. Safety, in terms of stimulators’ electrical performances, can be related mainly to two factors; the zero-net charge transfer to tissue and the heat generated by power dissipation at tissue. This paper presents a safety ensuring neurostimulator for retinal vision prostheses, featuring precise …
