Abstract
In recent years, triboelectric nanogenerators (TENGs) have developed rapidly and attracted the attention of researchers all over the world. Here, a novel waved-shaped triboelectric nanogenerator using the MgSiO3 powder (W-TENG) was developed. In this work, polyethylene terephthalate film and MgSiO3 powder form the triboelectric pairs. W-TENG devices can convert mechanical energy into electric energy. From the results, the maximum output power of a W-TENG can reach 184 µW. Additionally, a W-TENG can generate an open-circuit voltage (Voc) of 224.26 V, a short-circuit current (Isc) of 2.74 µA, and a transferred charge of 37.8 nC. Moreover, a W-TENG can serve as a self-powered human motion counter. This design describes a portable TENG device that can promote the self-powered human motion sensor application.
