Abstract
Magnetic resonant wireless power transfer (MRWPT) technology has great potential in delivering power to bio-implantable devices as it obviates the need to have expensive battery replacement surgery. However, no systematic design method has been reported in this important area. In this paper, a design method of MRWPT system for bio-implantable devices, including detailed procedures, is proposed to realize maximum power transfer efficiency. Considerations on the basic dimensions of the system are outlined, and ways to express the impedance coefficients matrix of equivalent circuit model as functions of system variables are given. Experiment is carried out to verify the validity and effectiveness of the proposed design method.
