About the book
Nanogenerators were invented by researchers to convert mechanical energy into electrical energy. Two different modes of nanogenerators, triboelectric and piezoelectric nanogenerators (TENG and PENG) are currently available. The working principle of the two types of nanogenerators is entirely different, but both belong to the same platform that can harvest waste mechanical energy from various sources, such as vibrations, biomechanical energy, wind, and water waves (blue energy). These nanogenerators stand unique from the existing energy harvesters because of advantages such as less weight, eco-friendliness, biocompatibility, low cost, energy harvesting 24/7, and so on. Various techniques are followed to fabricate these devices, since nanogenerators are not only used as energy harvesters, but can also be used as a self-powered sensors in various biomedical and electronical applications. External/internal integration of energy storage devices with the help of nanogenerators opens a path to a new research field of self-charging devices. These novel applications of nanogenerators attract researchers across the globe to initiate such research and contribute with their ideas to support this need. This book focuses on sharing a complete knowledge of the need for nanogenerators, their working mechanisms, fabrication of nanogenerators, various modes of energy harvesting, and their application in wearable electronics, Internet of Things, biomedicine, sensors, and self-charging devices.
