我们提出的设计，建模，制造和实验表征的电动无线电力传输（EWPT）接收器的低频（3）设备产生2.46 mW的平均功率（7.9 mW $\cdot $ cm-3功率密度）在4厘米的距离，从发射器线圈工作在821 Hz，并安全地在允许的人体暴露限制。该数据对应的归一化功率密度为21.9 mW $\cdot $ cm $^{-3}\，\，\cdot $ mT−2，比同类报道的器件高44%。基于这些结果，该设备显示出对移动的、可穿戴和生物植入设备的无线充电的极大适用性。[2020-0161]
We present the design, modeling, fabrication, and experimental characterization of an electrodynamic wireless power transmission (EWPT) receiver for low-frequency (3 device generates 2.46 mW average power (7.9 mW $\cdot $ cm−3 power density) at 4 cm distance from a transmitter coil operating at 821 Hz and safely within allowable human exposure limits. This data corresponds to a normalized power density of 21.9 mW $\cdot $ cm $^{-3}\,\,\cdot $ mT−2, which is 44% higher than similar reported devices. Based on these results, this device shows great suitability for wirelessly charging mobile, wearable and bio-implantable devices. [2020-0161]
