Abstract:
The world is entering a new era of the Internet of Things (IoT). Within the framework of IoT, billions of physical devices worldwide will connect to the Internet, uploading, downloading, and sharing data. If all the billions of IoT network nodes utilize chemical batteries, the follow-up maintenance and replacement tasks will be strenuous. How to address the power supply issue and guarantee the perpetual operation of those IoT network nodes is a challenging problem. Vibrations and wind are renewable energy resources that ubiquitously exist in our surrounding environment. Therefore, developing self-powered technology via scavenging energy from the ambient environment has gained enormous attention from the academic and industrial communities. In this talk, I will introduce a number of piezoelectric systems designed by us in the past few years for scavenging energy from vibrations or wind. Problems in practical energy harvesting will be pointed out. The motivation behind each design will be explained. Theoretical models of those electromechanical systems will be used to help elucidate their dynamic mechanisms.
