Abstract: The development of wearable flexible electronic devices is crucial for advancing applications in human motion monitoring, biomedicine, and smart sports. In this work, we introduce a MXene-based double-network conductive hydrogel (MD-hydrogel) for a high-performance triboelectric nanogenerator (MD-TENG). By incorporating sodium alginate (SA) into the hydrogel matrix, we significantly enhance its mechanical strength, enabling greater triboelectric contact and electrical output. Compared to conventional hydrogel TENGs, our MD-TENG exhibits 84 % higher open-circuit voltage (V OC ), 75 % higher short-circuit current (I SC ), and 84 % higher QSC. The V OC reaches 491.98 V, I SC 75.41 µA, transfer charge (Q SC ) 83.93 nC, and maximum power output 2.54 mW at 3 MΩ resistance, demonstrating superior energy harvesting performance. Furthermore, the MD-TENG is applied in football training, effectively sensing foot pressure and joint movements, providing real-time feedback for performance optimization and injury prevention. These findings highlight the MD-TENG’s potential for next-generation self-powered sensors in wearable electronics and sports monitoring.
