Implantable medical devices (IMDs) such as pacemakers and spinal cord neurostimulators must undergo reoperation to replace batteries. Therefore, developing a biocompatible wireless charging technology is necessary to overcome the problem.

ENERGYMINING realizes the wireless charging platform for IMDs in the depths of the body through ultrasound-driven triboelectric generating devices that convert mechanical energy into electricity.

The wireless charging platform can recharge the battery of IMDs located more than 10 mm deep in the body using biocompatible ultrasound.
