A Contrastive Studies between Magnetic Coupling Resonance and Electromagnetic Induction in Wireless Energy Transmission

Magnetic coupling resonance wireless energy transmission(Wireless electricity Witricity) is a new technology put forward by MIT in 2007.Witricity achieves middle distance wireless energy transmission through magnetic coupling resonance. Because of directional energy transmission and not affected by middle obstacles, it has good application prospect . In this paper simulation analysis and experiments have been carried out to make comparative analysis of Witricity and electromagnetic induction in wireless energy transmission. Compared with traditional electromagnetic induction energy transmission devices, the efficiency of the Witricity system is much higher. This investigation indicates that it is feasible to use Witricity to recharge batteries, particularly in implant devices.
