本文提出了一种多发射机、2.43 GHz射频（RF）无线电力传输（WPT）系统，用于为体内设备供电。结果表明，在典型的室内条件下，接收功率范围从微瓦到毫瓦跨越几个数量级。提出了一种可穿戴式双极化整流天线（整流天线），其设计适用于主极化不可预测的情况，如身体传感器的情况。电源管理电路被证明，即使在高度间歇性的条件下，最佳负载整流天线，并提高电压充电车载存储电容器。
This paper presents a multi-transmitter, 2.43 GHz Radio-Frequency (RF) wireless power transfer (WPT) system for powering on-body devices. It is shown that under typical indoor conditions, the received power range spans several orders of magnitude from microwatts to milliwatts. A body-worn dual-polarised rectenna (rectifying antenna) is presented, designed for situations where the dominant polarization is unpredictable, as is the case for the on-body sensors. Power management circuitry is demonstrated that optimally loads the rectenna even under highly intermittent conditions, and boosts the voltage to charge an on-board storage capacitor.
