Achieving Ultra‐Durability and High Output Performance of Triboelectric Nanogenerators

Abstract With rapid development of the Internet of Things (IoTs) era, a variety of miniaturized and distributed electronics appear in every corner of industrial production and daily life. The shortage of fossil fuels requires renewable clean energy to replace traditional energy to meet the needs of smart and low‐power devices. Triboelectric nanogenerator (TENG) is a new technology for converting high‐entropy mechanical energy into electric energy to power these devices. However, improving the output energy and durability of TENG remains a considerable challenge for practical applications. To solve these problems and push forward its commercialization process, this paper systematically reviews how to improve the durability of the sliding mode TENG (S‐TENG) from the aspects of material optimization and structural design. Besides, a variety of ways are introduced to improve the electric output of the S‐TENG under the premise of high durability. At last, challenges and future research focus in this field are also predicted, which provide a guideline for the research of the high electric output and ultra‐durability TENG for highly efficient energy harvesting and self‐powered sensing applications in the IoTs.
