Delivering power to an implanted device located deep inside the body is not trivial. This problem is made more challenging if the implanted device is in constant motion. This paper describes two methods of transferring power wirelessly by means of magnetic induction coupling. In the first method, a pair of transmit and receive coils is used for power transfer over a large distance (compared to their diameter). In the second method, an intermediate pair of coils is inserted in between transmit and receive coils. Comparison between the power transfer efficiency with and without the intermediate coils shows power transfer efficiency to be 11.5 % and 8.8 %, respectively. The latter method is especially suitable for powering implanted devices in the eye due to immunity to movements of the eye and ease of surgery. Using this method, we have demonstrated wireless power delivery into an animal eye.
向位于身体深处的植入设备供电并非易事。如果植入设备处于持续运动状态，这个问题将更具挑战性。本文描述了两种通过磁感应耦合进行无线电力传输的方法。在第一种方法中，使用一对发射和接收线圈在较大距离（相对于它们的直径）上进行电力传输。在第二种方法中，在发射和接收线圈之间插入一对中间线圈。有无中间线圈时的电力传输效率比较表明，电力传输效率分别为11.5%和8.8%。后一种方法特别适用于为眼睛中的植入设备供电，因为它不受眼球运动的影响且手术操作简便。使用这种方法，我们已经证明了可以向动物眼睛进行无线电力传输。
