摘要

本文提出了一种基于电感耦合的高效谐振调谐无线功率传输(WPT)链路，用于神经植入应用。使用线圈、负载和频率优化，电源链路的工作频率为10 MHz。损耗组织模型用于模拟组织中的功率损失，模拟的(HFSS)峰值SAR值在植入物接收的20 mW功率允许范围内。在功率传输范围为10 mm的情况下，植入线圈尺寸为250 mm2时的功率传输效率在82%左右。

An efficient wireless power link for neural implant

An efficient resonant tuned wireless power transfer (WPT) link using inductive coupling has been proposed for the neural implant application in this work. The power link is optimized for an operating frequency of 10 MHz using coil, load and frequency optimization. The lossy tissue model was used to mimic the power loss in tissue and the simulated (HFSS) peak SAR values were within the allowed limit for 20 mW power received at implant. The power transfer efficiency for implant coil sizes of 250 mm2 for a power transmit range of 10 mm was simulated using HFSS to be around 82%.
