Watt-level low-SAR near-field wearable wireless power transfer using an all-textile receiver
Near-field radiative Wireless Power Transfer (WPT)has the advantage of high-power WPT. In this paper, an all textile high-power WPT receiver is realized for the first time, using an embroidered coil and a printed tuning capacitor on a textile substrate. The proposed coil is demonstrated receiving over 3 W DC power at 6.78 MHz with a 23% end-to-end efficiency. A low Specific Absorption Rate (SAR) of 0.37 W/kg is observed, through full-wave simulation, for up to 10 W high frequency input to the on-body coil, demonstrating its suitability for wearable applications.

Abstract
Near-field radiative Wireless Power Transfer (WPT)has the advantage of high-power WPT. In this paper, an all textile high-power WPT receiver is realized for the first time, using an embroidered coil and a printed tuning capacitor on a textile substrate. The proposed coil is demonstrated receiving over 3 W DC power at 6.78 MHz with a 23% end-to-end efficiency. A low Specific Absorption Rate (SAR) of 0.37 W/kg is observed, through full-wave simulation, for up to 10 W high frequency input to the on-body coil, demonstrating its suitability for wearable applications.
