摘要

磁电换能器(ME)无线电力传输系统(WPTS)提供了一种为小型生物医学植入物供电的方法。但是，如果ME接收器不对齐，则传输到负载的无线功率可能会大大降低。使用致动器和物理旋转或移动发射线圈的动态发射线圈减少了发射器和接收器之间的不对准。我们使用动态发射机与静态发射机(不移动或旋转的线圈)对WPTS的预期功率增益进行建模。我们通过实验表明，在WPTS中，对于给定的未对准的ME接收器，添加单个伺服电机以使动态发射线圈比其他相同的静态发射线圈增加可用于负载的功率2.4倍。

A Dynamic Transmit Coil for Wirelessly Powering Small ME Transducer based Biomedical Implants

Magnetoelectric transducers (ME) wireless power transfer systems (WPTS) offer a way to power small biomedical implants. However, if the ME receiver becomes misaligned the wireless power delivered to the load can be dramatically reduced. A dynamic transmit coil using actuators and physically rotating or moving the transmit coil reduces the misalignment between the transmitter and the receiver. We model the expected power gains a WPTS has using a dynamic transmitter versus a static transmitter (a coil that does not move or rotate). We experimentally show that adding a single servo motor to make a dynamic transmit coil increases the power available to load by a factor of 2.4 over an otherwise identical static transmit coil for a given misaligned ME receiver in a WPTS.
