Miniaturized, multi-functional implantable medical devices provide continuous health monitoring but encounter significant power supply challenges. Wiring is impractical due to infection risks and bulk, while batteries have limited lifespans and potential health risks if they leak. Therefore, an optimal power solution must ensure tissue safety, deliver sufficient energy, and minimize size to make the device less invasive. Wireless power transfer methods, including radio frequency, inductive coupling, ultrasound, and capacitive coupling, offer potential solutions but face hurdles such as receiver size constraints, sensitivity to misalignment, transmission loss, and safe power delivery through biological tissues. Magnetoelectric (ME) technology is emerging as a powerful solution for wirelessly powering devices deep within the body offering several key advantages, including high efficiency in a compact form factor and excellent performance against misalignment.
