Simulation Analysis of Wireless Power Transmission System for Biomedical Applications
In recent years,more and more implantable medical devices have been used in the medical field.Some of these devices,such as brain pacemakers,require long-term power support.The WPT(wireless power transmission)technology which is more convenient and economical than replacing the battery by surgery,has become the first choice of many patients.In this paper,we design a WPT system that can be used in implantable medical devices,simulate the transmission efficiency of the system in the air and in the head model,and simulate the SAR value when the system working in the head model.The results show that when implantation depth of the secondary coil is 3 mm,the efficiency of the system can reach 45%,and the maximum average SAR value is 2.19 W/kg,slightly higher than the standard of IEEE.
