摘要

磁共振耦合无线电力传输(WPT)系统作为一种为植入式医疗设备(imd)供电的有效方法，越来越受到人们的关注。功率传输效率是WPT系统的一个重要特性。它的特点是WPT线圈的耦合和质量因素。在高耦合和高质量因数的条件下，获得了最大的功率传输效率。这在很大程度上取决于WPT线圈的几何参数。本文提出了一种迭代设计和优化植入线圈的方法，该线圈的尺寸限制在20mm，距离为30mm，工作频率为13.56 MHz，在ISM频段内。该方法的目的是寻找最优的几何参数，使功率传输效率最大化。所设计的线圈的效率高达83%。最后，利用Ansys Maxwell 3D进行有限元仿真，验证了所得结果。

Iterative Method Based Optimization of Wireless Power Transfer for Biomedical Implants

Magnetic resonance coupling wireless power transfer (WPT) systems have gained increasing interest as an effective method for powering implantable medical devices (IMDs). Power transfer efficiency is a very important characteristic of WPT systems. It is characterized by the coupling and quality factors of the WPT coils. The maximum power transfer efficiency is obtained for high coupling and quality factors. It greatly depends on the geometrical parameters of the WPT coils. This paper presents an iterative procedure to design and optimize an implant coil restricted to a small size of 20mm at a distance of 30 mm, with an operating frequency of 13.56 MHz within the ISM frequency band. The proposed method aims to find the optimal geometrical parameters that maximize the power transfer efficiency. The designed coils give a high efficiency of about 83%. Finally, the finite element simulation with Ansys Maxwell 3D validates the obtained results.
