摘要

Active implantable medical devices (AIMDs) like implantable cardiac pacemakers play very important role in extending lives of patients with some cardiovascular diseases. The life of implantable device depends on life of battery. If this device can be charged from outside with power transfer device, then the cost of surgical procedures for patient can be saved. One must ensure, while transferring this power there should not be any abnormal effect on human body tissues. Wireless recharging of such devices through magnetic resonant coupling is of concern and hence the topic of more research to have uninterrupted supply from battery. The technique of wireless power transfer, primary or transmitting coil is assumed to be on body and receiver coil is assumed to be inside the human body. Several critical aspects need to be studied while designing coil for wireless power transfer (WPT). One of which is choice of operational frequency. In this research experiment, designed circuit is tested for checking power transfer was studied. Effect of the distance between primary and secondary coil affects the efficiency of power transfer. Authors also tied to test this for using different medium like air, placing 80 GSM paper and cloth. It is found that the medium between the primary and secondary affects the transfer of power. Careful thought needs to be given while designing power transfer system.
