Abstract
Conductive hydrogel is a high-performance conductive electrode that can be used for flexible and stretchable sensors. Furthermore, the self-powered sensor devices integrated with conductive hydrogel conductive can play the role in dance posture monitoring. In this work, we proposed a carboxymethyl chitosan (CMCh)-Fe/LiCl hydrogel-based triboelectric nanogenerator (CL-TENG) to harvest human motion mechanical energy. Based on the experimental results, the average transmissivity of CMCh-Fe/LiCl hydrogel can arrive at 91.53%. Also the CMCh-Fe/LiCl hydrogel has a high rate of mechanical healing, especially at high temperatures. The CL-TENG can reach the maximum power density of 81.48[Formula: see text]mW/m2 when the external load is 200[Formula: see text]M[Formula: see text]. The open-circuit voltage ([Formula: see text]) and transferred charge ([Formula: see text]) of CL-TENG can arrive at 96[Formula: see text]V and 32.4[Formula: see text]nC, and the short-circuit current ([Formula: see text] of CL-TENG can reach 1.2[Formula: see text][Formula: see text]A. The CL-TENG can also serve as the self-powered dance motion sensor to monitor the action specifications of actors in cheerleading performance. This research will promote the development of dance pose sensors.
