Effects of the Human Body on Wearable Wireless Power Transfer Systems
Keywords:Human body, wearable, wireless power tranfer, SCMR
In this paper, the effects of different parts of the human body on a wearable Wireless Power Transfer (WPT) system are examined. A Strongly Coupled Magnetic Resonators (SCMR) WPT system operating in the ISM band 40.68 MHz is used in this study. The results show that when the WPT system is placed directly on the human body its Power Transfer Efficiency (PTE) is reduced by 13% on average in both simulations and measurements. These losses are attributed to the material properties of the human body. Also, different parts of the human body cause different drops in PTE due to their different shapes and geometries.
