A leadless intracardiac pacemaker powered by energy harvested from cardiac motion was developed in a preclinical study.
2

The device incorporates two triboelectric nanogenerators that convert heartbeats into electrical energy.
3

In vivo testing showed that the TENG system could increase heart rates while maintaining stable electrical capture.
4

The device demonstrated a volumetric power density of 277 μW/cm³, exceeding previously reported implanted nanogenerators.

Chronic evaluation in one swine showed stable cardiac function without significant complications after 4 weeks.
