Abstract
ABSTRACT Recently, sports monitoring sensors based on flexible wearable technology have attracted much attention. Here, we reported a P(VDF-co-HFP)/MXene-based triboelectric nanogenerator (PM-TENG) to harvest bio-mechanical energy. The introduction of MXene can significantly improve the dielectric constant of P(VDF-co-HFP), thereby achieving higher electron harvesting ability. The PM-TENG can obtain the maximum instantaneous power of 1.68 mW contacted with a resistance of 4 MΩ. Furthermore, the PM-TENG can be also integrated inside the mask to monitor changes in respiratory status before and after basketball exercise. Meanwhile, the PM-TENG installed inside the shoes can be used to distinguish different gaits in basketball, which will be used to assist in basketball training. This flexible sport sensor demonstrates potential application value in basketball training assistance.
