Study on Magnetically Coupled Intrabody Communication Dynamic Optimization Regarding Two-Coil Power-Transfer System Using L-section Matching Network

Abstract

This study examined a novel intrabody communication method using magnetic coupling. For designing transceivers utilizing this communication method, it is important to understand the power-transfer characteristic between the sending and receiving coils of the transceivers and to develop a technique for maximizing the transceiver efficiency. This study targeted a two-coil wireless power-transfer system with an L-section matching network. The computer simulation results showed that 1) the maximum power-transfer efficiency (PTE) was obtained by adjusting the matching network, and 2) the optimal PTE was achievable. In addition, this study conducted experiments and derived similar results from part of the simulation. The proposed wireless power-transfer system is promising as a magnetic intrabody communication system.
