Wireless Energy Transmission System for Implantable Device

Abstract

A wireless energy transmission system based on magnetic coupling resonance was put forward for implantable device. Combining the calculation of self-inductance and mutual inductance between the transmitting and receiving spiral coil, the paper used circuit theory to model and simulate the characteristic of transmission system, the coil parameters including radius and number of turns can be determined accurately. The wideband Class-E power amplifier was used to drive the transmitting coil, its structure and working state were described in detail. Finally this paper carried on the experimental analysis to verify the theoretical derivation and system characteristics.
