In vitro and in vivo studies on the biocompatibility of a self-powered pacemaker with a flexible buckling piezoelectric vibration energy harvester for rats.

ABSTRACT:

Background

Scavenging energy from biomechanical motions in vivo by energy converting devices, i.e., implantable harvesters, to obtain sustainable electrical energy is the ideal way to power implantable medical devices which require long term and continuous power supply. A novel self-powered cardiac pacemaker is designed to achieve self-powered pacing. The kinetic energy of the heart was collected by an implanted piezoelectric energy collector and supplied to the cardiac pacemaker, and then the cardiac tissue was stimulated by the pacing electrode pierced from the outside of the heart to realize effective pacing effect and self-powered pacing. In this study, we evaluated the stability and biocompatibility of our previously described flexible buckling piezoelectric vibration e
