Abstract
In recent years, the development of triboelectric nanogenerator (TENG) technology has made great progress. However, most of the work focuses on the improvement of triboelectric materials and the optimization of device structure. In this work, we introduced a novel triboelectric nanogenerator integrated with wave structure electrode (W-TENG). Compared to the TENG with traditional flat plate electrode, the W-TENG with wave structure electrode can achieve higher output performance. The maximum short-circuit current (Isc), transfer charge, and open-circuit voltage (Voc) of 2.56 μA, 29 nC, and 74 V were obtained at 300 N. Correspondingly, the instantaneous output power of W-TENG illustrates the maximum value of 0.94 mW at 6 Hz. In addition, the output voltage signal of W-TENG can clearly reflect the different postures in football, and the W-TENG can perform real-time football monitoring. This mechano-electrical energy harvester and the corresponding self-powered monitor can promote the intelligent sports development.
