A Study of Wearable Wireless Power Transfer Systems on the Human Body

A study is performed to evaluate the performance of wearable Wireless Power Transfer (WPT) systems on various parts of the human body. Specifically, the effects of the human body on the Power Transfer Efficiency (PTE) of a Conformal Strongly Coupled Magnetic Resonance (CSCMR) WPT system is systemati...
