Dissolving pacemakers are the future of electronic medicine and last updated 2021-07-17 21:42:31-04 CHICAGO, Ill. â Cardiac pacemakers require wires to be implanted in the chest to help control the patientâs heartbeat. But now researchers have developed the first-ever wireless, battery-free pacing device that doesnât have to be removed. Itâs an implantable electrical device that dissolves inside your body after itâs done with its work. âOne of the key features of this system is very thin, silicon, nanomembrane. Actually, this is the only active part of this device,â said Yeonsik David Choi, lead developer of the device in the Rogers Research Group at Northwestern University and lead author of the study.
