Abstract

A wireless power delivery system for a biomedical retinal prosthesis is presented and analyzed. Due to large and fast coupling variations in the inductively powered retinal implant caused by the eye movements, excessive power has to be controlled. This power delivery setup enables excessive power control measurements by featuring movements of an eye model. The turning of the eye model is controlled with a microcontroller board. Measurements and control of the model is automatized using Matlab. Measurement results show an enormous reduction of the transmitted power for large eye movements and therewith the need for power control in biomedical implants.
