Utilizing the piezoelectric effect of ZnO nanowires, nanogenerators have been fabricated for producing an output of 10–20 V. On page 280 , Zhong Lin Wang demonstrates a self‐powered system by integrating a nanogenerator with sensors, energy storage units, a data processor, and a wireless transmitter, which can operate without a battery by harvesting mechanical energy from the environment. Such systems have application in biomedical science, environmental monitoring, structural monitoring, and personal electronics.
