A research team at the Center for Nanoparticle Research, within the Institute for Basic Science (IBS), has developed a wearable and implantable device that measures electrophysiological signals and applies electrical and thermal stimulations. It provides information on muscle and cardiac dysfunctions, and thus could be implemented for pain relief, rehabilitation, and prosthetic motor control. As the first soft implant able to record cardiac activity in multiple points of a swine heart, this prototype, described in Nature Nanotechnology, could contribute to the research and production of future bioelectronics.
