Abstract
ABSTRACT Recently, research about the intelligent sports equipment based on triboelectric sensor for athlete posture monitoring has made progress. However, the exploration of new triboelectric materials remains an important challenge to be faced. Hence, we ingeniously design a polydimethylsiloxane (PDMS)/silanized graphite oxide (SGO)-based triboelectric nanogenerator (PS-TENG) for running posture and physical health monitoring. The introduction of SGO has improved the electron capture capability of PDMS, thereby achieving high output of PS-TENG. From the results, under an 60 MΩ resistance, the power density of PS-TENG reaches a peak of 1780 mW·m−2. Furthermore, athletes undergo various postures during the running process, so monitoring special postures is very meaningful, such as jogging, long jump, walking, etc. Especially, according to the self-charging mechanism, PS-TENG can indirectly evaluate physical energy analysis during running by storing electrical energy in capacitors. This triboelectric sensor can assist in posture monitoring and physical fitness monitoring during running.
