Abstract

To solve the parameter selection problem in the design of visual prosthesis wireless power transfer system

this paper precisely models visual prosthesis wireless power transfer system on the basis of biological capacitance.Based on this model

the secondary coil circuit of the wireless power transfer system is optimized

with which the energy transfer efficiency is improved obviously compared to the traditional resonant coupling method.Experimental measurement data from the comparison and analysis between two different-sized coils highly match the simulation data in the modeling

and it verifies the correctness of the modeling and the feasibility of the optimization scheme

providing theoretical reference to the coil option of visual prosthesis clinical application and the design of wireless energy transfer system.
