Abstract
Recently, intelligent wearable flexible sensors for sports monitoring have received extensive attention. Here, we designed a AGO hydrogel-based triboelectric nanogenerator (A-TENG) for bio-mechanical harvesting and basketball posture monitoring. The AGO hydrogel can be rapidly prepared only by a simple mechanical mixing method, and there is no need to heat and add cross-linking agent during the preparation process. Besides, the A-TENG has good environmental adaptability, and the change of environmental humidity will not have irreversible impact on it. Furthermore, according to results, when the external resistance is 9[Formula: see text]M[Formula: see text], the output power density of A-TENG device reaches a maximum of 3.1[Formula: see text]W/m2. The self-powered sensor based on A-TENG device can be used to monitor the basketball posture. In the future, the A-TENG device can have high application value in basketball training, in order to serve intelligent sports monitoring.
