Abstract: Triboelectric nanogenerator (TENG) technology can harvest mechanical energy to generate electricity based on friction electrification. Compared with the traditional electromagnetic induction technology, TENG has the advantages of high output voltage, light weight, small volume, flexibility, different shapes and high compatibility. In this work, the research progress and potential application of TENG technology based on our group's work were reviewed. The four modes and basic working principles were first introduced. Then, the research progress of TENG technology used as power source, voltage source, signal source and control source was discussed in detail. Finally, the industrial application prospect of the TENG technology was prospected.
