强反应近场无线电力传输（WPT）系统在其附近的人的身体组织中感应电场。这可能会通过干扰医疗植入物造成潜在的直接健康危害或间接风险。在本文中，安全准则和基本的人体与电磁近场的WPT的耦合机制进行审查，以及方法和仪器的安全性的演示系统之间的100 kHz和50 MHz的操作。在此基础上，国家的最先进的数值和实验技术的优点和缺点进行了讨论，并适用于一个通用的WPT工作在8 MHz。最后，确定了当前的研究需求，包括：1）扩展植入物覆盖人群的安全指南; 2）计算效率更高的全波求解器; 3）更高质量的人体模型，覆盖不同人群，包括改进的神经组织模型; 4）WPT频率范围的实验剂量测定方法; 5）证明特定WPT安全性的产品标准。
The strong reactive near-field wireless power transmission (WPT) systems induce electric fields in the body tissue of persons in their close vicinity. This may pose potential direct health hazards or indirect risks via interference with medical implants. In this paper, the safety guidelines and the fundamental coupling mechanisms of the human body with the electromagnetic near fields of WPT are reviewed as well as the methodology and the instrumentation for the demonstration of the safety of such systems operating between 100 kHz and 50 MHz. Based on this review, the advantages and shortcomings of state-of-the-art numerical and experimental techniques are discussed and applied to a generic WPT operating at 8 MHz. Finally, current research needs are identified which include: 1) the extension of safety guidelines for coverage of persons with implants; 2) more computationally efficient full-wave solvers; 3) higher quality human models which cover different population groups and include improved models of nerve tissue; 4) experimental dosimetric methods for the WPT frequency range; and 5) product standards to demonstrate safety of specific WPT.
