Abstract: As the development of the Internet of Things (IoT), trillions of widely-distributed devices are integrated for health monitoring, biomedical sensing, environmental protection, infrastructure monitoring, and security. The traditional technology for powering these devices is using batteries, which might not be an optimal solution due to the limited lifetime, difficulties for replacement and maintenance, and potential environmental issues. To provide a sustainable power solution, triboelectric nanogenerator (TENG) has been developed since 2012 for high-efficiency mechanical energy harvesting from ambient environment. Starting from the fundamental studies of TENG operation cycles through the voltage-charge plots, a series of important research have been conducted, including: (1) maximizing energy output and establishing figure-of-merits as standards for quantitative evaluation of TENG; (2) triggering electrospray ionization process towards unprecedented controls and ultrasensitivity in mass spectrometry analysis; (3) developing effective energy storage solution through the designed charging cycles of TENG. These studies will drive the further development of TENG technology for broad applications and industrializations, towards high-efficiency self-powered systems.
