Abstract
Recently, intelligent sports monitor devices based on self-powered sensor technology have received widespread attention. Here, we designed a triboelectric nanogenerator based on a poly(vinylidene fluoride-vinyl chloride) PV(DF-A) film and a polydimethylsiloxane (PDMS) film (PP-TENG) to harvest bio-mechanical energy and serve as the basketball training sensor. After experimental testing, the electron loss ability of the PV(DF-A) film is greater than that of a polyvinylidene fluoride film. Also, the open-circuit voltage (Voc) and short-circuit current density (Jsc) of PP-TENG can get to 1856.4 V and 269 mA m−2, respectively. The PP-TENG can obtain a maximum power density of 130.28 W m−2. Moreover, the PP-TENG sensor can monitor various gait patterns of players in basketball and achieve auxiliary analysis of basketball training strategies. This research will promote the development of intelligent basketball training sensors.
