A research team at the Institute for Basic Science's Center for Nanoparticle Research in Seoul, South Korea, has developed a wearable and implantable device that measures electrophysiological signals and applies electrical and thermal stimulations as needed.

The team says the device provides information on muscle and cardiac dysfunctions, and could be implemented for pain relief, rehabilitation, and prosthetic motor control.

In addition, this prototype is the first soft implant that can record the cardiac activity in multiple points of a swine heart, and it will contribute to the research and production of future bioelectronics.

The researchers also used the device on human skin to record the electrical activity of heart and muscles. Worn on a forearm, the device simultaneously monitored electromyogram signals, and delivered electrical or thermal stimulations that could be employed in therapeutic applications.
