A drum structure triboelectric nanogenerator based on PS/MXene for football training monitoring

Recently, flexible multifunctional sensors have attracted widespread attention from around the world. Here, we propose a novel PS/MXenebased triboelectric nanogenerator (PM-TENG), which has a drum structure design. Through comparative experiments, the optimal ratio of polystyrene (PS) materials was explored. The PS film and nylon film form the triboelectric materials, and copper foil acts as the conducive electrode. From the results, the open-circuit voltage (Voc) and short-circuit current (Isc) of the PM-TENG based on 35 mg/ml content of PS can reach 141 V and 5.9 mu A, respectively. In addition, when the resistance value of the external load is 50 MO, the PM-TENG exhibits a maximum output power of 123 mu W. Due to its excellent flexibility, the PM-TENG can be installed on the shoulders, neck, wrist, elbow, knee, and ankle to achieve all-round motion monitoring of football players. This research can promote the application of TENG sensors in the football monitoring field. (c) 2023 Author(s).
