Air/liquid-pressure and heartbeat-driven flexible fiber nanogenerators as a micro/nano-power source or diagnostic sensor have been successfully demonstrated
Self-powered system with wireless data transmission—a system composed of integration of an NG, power conditioning electronics, sensor, and RF data transmitter. Wireless signals sent out by the system were detected by a commercial radio at a distance of 5–10 m. This opens potential application in wireless biosensing, environmental/infrastructure monitoring, sensor networks
Self-powered environmental sensor system driven by nanogenerators, such a system is made of a ZnO nanowire-based nanogenerator, a rectification circuit, a capacitor for charge storage, a signal transmission LED light, and a carbon nanotube-based Hg2+ ion sensor. It is the first demonstration of a nanomaterial-based, self-powered sensor system for detecting a toxic pollutant
Replacing a battery by a nanogenerator with 20 V output managed to drive a commercial buck convertor board, and a regulated voltage of 1.8 V with constant current load was achieved to drive an electrical watch for more than 1 minute after the board was charged by the NG with 1000 cycles of deformation. This is the first time that an NG works as a battery part for real commercial consumer electronics.
