First demonstration of a self-powered cardiac pacemaker

A self-powered artificial cardiac pacemaker that is operated semi-permanently by a flexible piezoelectric nanogenerator has been developed by researchers. The team’s newly designed flexible piezoelectric nanogenerator directly stimulated a living rat’s heart using electrical energy converted from the small body movements of the rat. This technology could facilitate the use of self-powered flexible energy harvesters, not only prolonging the lifetime of cardiac pacemakers but also realizing real-time heart monitoring.
