A Spring Structure Triboelectric Nanogenerator for Human Gait Monitoring System

Abstract

In recent years, many researchers have developed the triboelectric nanogenerators (TENGs) technology to harvest mechanical energy. Here, we proposed a spring-like supporting structure triboelectric nanogenerator (S-TENG) to gain mechanical energy and translate them into electrical energy. From the results, the open-circuit voltage ([Formula: see text]) of S-TENG can arrive at 390[Formula: see text]V, and the short-circuit current ([Formula: see text]) of S-TENG can reach 13.13[Formula: see text][Formula: see text]A. Also, the transferred charge of S-TENG can get to 130[Formula: see text]nC, and as for the maximum output power of S-TENG with the size of [Formula: see text][Formula: see text]cm, it can reach 1.44[Formula: see text]mW. Besides, the electrical output signal of S-TENG can reflect the human motion state such as walking, running and jumping. This design not only greatly promoted the TENGs in mechanical energy harvesting but also the development of self-powered human motion sensor.
