Jacob T. Robinson, Kaiyuan Yang Rice University, Houston, TX Wireless, batteryless, and miniaturized implants promise transformative therapies for various neurological, psychiatric, and cardiac disorders. Beyond conventional batterypowered bulky implants with leads, miniaturized implants promise drastically reduced infection risk and surgical complexity, and improved patient acceptance and precision. Despite significant efforts on wireless power transfer (WPT) for implants, most demonstrations are not sufficiently reliable to sustain practical usage, when misalignment between the external hub and the implant persists due to motions, respiration, and heart beating, as well as the restricted device orientation during implantation (e.g. in spinal cords or vessels). The power transfer efficiency (PTE) of WPT degrade drastically under misalignment, rendering the system unstable and unusable (Fig. 17.1.1). Transmitting
