Abstract:: Abstract: In order to solve the problem of energy supply shortage in traditional implantable human medical devices, a wireless power transmission system can be designed for medical devices such as cardiac pacemakers by using resonant coupling wireless power transfer technology. In accordance with the small size of the implantable medical devices, the 8-shaped coil structure is introduced. The finite element simulation software is used to analyze the effects of the relevant parameters on output power, and the optimal solution of the system parameters is obtained. The distribution of magnetic induction and electric field intensity generated in the human body model was analyzed. A comparative analysis was made on the limits established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) to assess the safety of electromagnetic exposure of the system. The results show that the system can safely implement wireless power transmission.
