Energy-harvesting gizmo powers medical implants using your own heartbeat

Apr 25, 2019   |   Digital Trends

“In this work, we developed a new design for energy harvesting that can be miniaturized and integrated within existing pacemakers,” Zi Chen, an assistant professor in the Thayer School of Engineering at Dartmouth, told Digital Trends. “It uses dual-cantilever structured thin films made of piezoelectric materials for effective conversion of kinetic energy into electrical energy. The heart’s motion results in the motion of the pacemaker lead, and hence the deformation of the thin films, which is then converted into electrical energy by virtue of the piezoelectric material.”
