Triboelectric nanogenerator for weak energy harvesting

Advanced energy technology has been promoting the development of human society. As a new type of energy collector, triboelectric nanogenerator is based on triboelectrification and electrostatic induction. It is a sustainable, stable and green energy supply. However, in the case of weak energy harvesting, the design of triboelectric nanogenerator should be careful, especially in terms of sensitivity and efficiency. This paper outlines a variety of triboelectric nanogenerator designs for weak energy harvesting, as well as the working mechanism and applications, which in turn presents an outlook for medical equipment, sustainable system and security devices.
