Wireless Charging Device for Artificial Cardiac Pacemaker

摘要

To overcome the limitation of energy supply for artificial cardiac pacemaker, this paper investigated a wireless charging device based on the magnetic coupling resonant wireless transfer (MCR-WPT) technique. We designed the bilayer coupled coils for energy transmission, which had twice power factor than monolayer coils. The frequency is 200 kHz when the MCR-WPT system was in resonance. Furthermore, we put the titanium alloy case behind the receiver coil to simulate the environment of artificial cardiac pacemaker. At last, we have done the charging experiment.
