Abstract

This paper addresses the latest advancements in the application of computational electromagnetics and smart telemetry systems to the development of a retinal prosthesis to restore the sight in the blind. Numerical methods and models have been developed to: (a) accurately characterize the thermal increase in the human head and eye associated with the operation of the retinal prosthesis; (b) determine the current spread in the retinal tissue associated with the implanted microstimulator array; and (c) design a high data rate smart telemetry system with extended capabilities with respect to traditional telemetry systems.
