A Flexible Triboelectric Nanogenerator Based on MXene for Jumping Motion Monitoring

Recently, owing to the development of artificial intelligence technology, human posture recognition has aroused great interest in the academic community. Thus, we designed a triboelectric nanogenerator based on PDMS layer and MXene/PDMS layer (PM-TENG) to obtain mechanical energy and sense human posture. According to the results, the open-circuit voltage ([Formula: see text] of PM-TENG can arrive at 372 V, and the short-circuit current ([Formula: see text] of PM-TENG can reach 16.21 [Formula: see text]A, respectively. Due to its highly sensitive sensor to complex human motor states like folding, stretching, squeezing, and tapping, it can not only be used to harvest mechanical energy from its surroundings, but also to monitor human movement and behavior. Thus, human motion behaviors like walking, leg lifting, and light and high jumps may be tracked and identified by reading pulse electrical signal production. This research will provide a new idea for human motion posture monitoring.
