本研究解决了需要向嵌入导电块内的设备进行无线电能传输的应用问题。涡流的产生会形成与发射机磁场相反的磁场，大幅降低耦合系数，进而降低传输效率。文中以钛植入体为案例进行研究分析，设计了负载以确保1 mA的恒定电流。搭建实验装置并评估，对比接收器嵌入植入体时测得的电参数差异，同时考虑多种缓解或避免涡流影响的方案。结果表明，若不仔细关注接收器所在空腔的几何形状，此类系统在技术上可能不可行。
英文摘要
This work addresses the problem of applications that require wireless power transfer to devices embedded within conductive blocks. The emergence of eddy currents tends to generate a magnetic field opposing that of the transmitter, drastically reducing the coupling coefficient and, consequently, the efficiency of the process. A case study involving a titanium implant is presented and analyzed with a load designed to ensure a constant current of 1 mA. An experimental setup is assembled and evaluated to compare differences in the measured electrical parameters when the receiver is embedded in the implant, considering several solutions that mitigate or avoid the effects of eddy currents. The results show that such a system may be technically unfeasible if careful attention is not paid to the geometry of the cavity in which the receiver is positioned.
