"Revolutionary Wireless Charger Implanted Inside Humans Developed by Chinese Scientists"
Originally Published 2 years ago — by South China Morning Post
Chinese scientists have developed a biodegradable wireless energy receiving and storage device that can power bioelectronic implants, such as drug delivery systems. The device consists of a magnesium coil that charges when an external transmitting coil is placed on the skin above the implant. Power passes through a circuit and enters an energy storage module made of zinc-ion hybrid supercapacitors. The prototype device, contained in a flexible biodegradable chip-like implant, integrates energy harvesting and storage. Tests on rats showed that the device can function effectively for up to 10 days and fully dissolves within two months. The researchers believe this development is a significant step forward in advancing transient implantable bioelectronic devices.
