A Stretchable Triboelectric Nanogenerator Integrated Ion Coagulation Electrode for Cheerleading Monitoring

With the evolution of flexible electronics, the use of flexible wearable triboelectric nanogenerator (TENG) devices has become conceivable. However, the majority of flexible electronic goods are unable to achieve the requirements for high elasticity, transparency, and conductivity at the same time. We employed a carboxymethyl chitosan (CMCh)-Fe hydrogel with a double-network polymer ion conductor that displays outstanding elasticity (> 1050%) and transparency (> 90%). The CMCh-Fe hydrogel TENG (CF-TENG) can obtain energy from human motions. The CF-TENG device may also be configured as a self-powered smart exercise belt sensor to monitor arm extension movements. This might be a new method to get your hands on the next generation of environmentally friendly wearable and activity-monitoring equipment.
