A Flexible Triboelectric Nanogenerator Integrated with CMCh-Fe/LiCl Hydrogel Electrode for Cheerleading Monitoring.

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 mW/m2 when the external load is 200 M Ω. The open-circuit voltage ( V oc ) and transferred charge ( Q sc ) of CL-TENG can arrive at 96 V and 32.4 nC, and the short-circuit current ( I s c) of CL-TENG can reach 1.2 μ 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.
