Analysis of Wireless Energy Transmission for Implantable Device Based on Coupled Magnetic Resonance

WiTricity is a new technology for transmitting energy wirelessly via resonant coupling in the non-radiative near-field. In this paper, design of energy transmission system for implantable devices base on WiTricity is performed, the influence of system structural parameters on the energy transmission efficiency is investigated, the relations between the energy transfer efficiency with the transmission distance are analyzed, and also the frequency values of resonant coils with different parameters have been figured out.
