The development of self-powered smart biosensors has attracted great attention due to their potential applications in human motion monitoring and energy collection systems. Here, a newly designed triboelectric nanogenerator (PSP-TENG) composed of the PU sponge, polytetrafluoroethylene, and polydimethylsiloxane for monitoring rear leg rotation motion in artistic gymnastics has been developed. The PSP-TENG can monitor the buffering and stretching time of rear leg rotation and identify the angle between the hip, knee, and ankle during the stretching stage. Furthermore, the PSP-TENG has the function of converting measured signals into power signals, which can convert collected human motion mechanical energy into electrical energy to power wearable devices. The development of PSP-TENG has made contributions to the field of human motion monitoring, providing ideas for new energy and technologies to improve the environment and promote a virtuous ecological cycle.
