A Handy Wireless Charging Prototype for Bio-medical Implantable Devices

Abstract

Wireless power transfer technology is emerging fast in the modern era, which turns out to be a broad research area applicable for healthcare systems like biomedical implantable devices. Where, receiver coil is placed inside the human body and transmitter coil is positioned out of the body. In such a system, coil’s size, weight and coupling factors are the critical and important aspects need to be considered. In this paper, a simulation model is designed, whose dimensions are varied under distinct operating conditions. An electromagnetic field analysis is performed to examine the inductive characteristics of WPT coils. The size of the WPT coils is adjusted for good coupling factor and some significant results are reported. Further, to validate the idea, a handy wireless charging prototype is implemented and tested at laboratory level. Some experimental results are obtained and relevant discussions are presented.
