A Design of Honeycomb-shape Coil for Wireless Charging of Leadless Cardiac Pacemaker

In this paper, a novel transmitting coil for magnetic resonance wireless power transfer is designed, which is called honeycomb-shape coil. It surrounds the human body and can form a stronger magnetic field than the traditional coil. Take the leadless cardiac pacemaker as an example, suppose it is on the left side of the heart and design the LCC-C compensation topology circuit to build an energy transmission system working at 13.56MHz, the simulation results show that the transmission efficiency is approximately 0.9%. When the received power is 1mW, the maximum average specific absorption rate (SAR) of the system is 0.240W/kg, which accords with the EN62209-1 human electromagnetic radiation standard.
