A Device for Wireless Powering of Battery-Free Implants via Inductive Coupling

摘要

A device for wireless powering of battery-free implants with 500-mW power consumption is considered. The design of the device is described. The device provides relatively high stability of operation (power drop less than 10%) in the case of coil misalignment typical of medical applications (up to 20 mm). The results of engineering tests and tests with a tissue-like phantom (isotonic solution) are presented.
