Abstract :The triboelectric nanogenerator is a state-of-the-art device for addressing the growing problem of meeting the world\`s ever-increasing energy needs by converting mechanical energy into electrical energy. Using the popular semiconductor SnO2 nanostructured thin films as a triboelectric layer over contact regions, as opposed to polymers with lesser performance, increases the output power and life time of nanogenerators. In order to design a triboelectric nanogenerator, deposited thin film SnO2 is used as a friction layer with Ag electrode after heat-treatment at 623 K with a contrary layer of PMMA poly insert ignore into journalissuearticles values(methyl-methacrylate); with ITO electrode. The structural and electrical properties were analyzed by using scanning electron microscopy insert ignore into journalissuearticles values(SEM);, electro-impedance spectroscopy insert ignore into journalissuearticles values(EIS); and atomic force microscopy insert ignore into journalissuearticles values(AFM); measurements. The increased output power of the triboelectric nanogenerator is attributed to the nanoscale PMMA contact charge created by tunneling electrons in the SnO2/Ag nanocomposite thin film layer. Due to its proximity to the PMMA/ITO surface, the SnO2/Ag layer causes electron field emission, and tapping the SnO2/Ag layer may result in electron cloud overlap. Similar to a semiconductor/insulator interface, the Fermi level of SnO2 plays a crucial role in electron transport. The system efficiency stated as a touch detector in a conventional keyboard that generates its own power is revealed in part by an analysis of its operating state up to the 4V.
