随着生物医学植入物和可穿戴设备的尺寸变得更小，对以更高功率密度输送功率的方法的需求正在增长。无线地输送功率的最常见的方法，感应耦合线圈，遭受非常小尺寸的接收线圈的差的功率密度。另一种策略是将电力无线传输到磁电（ME）或机械磁电（MME）接收器，这些接收器可以在给定频率下以小得多的尺寸有效地工作。这项工作研究了ME和MME换能器作为无线功率接收器的有效性，用于非常小的生物医学植入物（
As the size of biomedical implants and wearable devices becomes smaller, the need for methods to deliver power at higher power densities is growing. The most common method to wirelessly deliver power, inductively coupled coils, suffers from poor power density for very small-sized receiving coils. An alternative strategy is to transmit power wirelessly to magnetoelectric (ME) or mechano-magnetoelectric (MME) receivers, which can operate efficiently at much smaller sizes for a given frequency. This work studies the effectiveness of ME and MME transducers as wireless power receivers for biomedical implants of very small (
