Here, a multinetwork PD hydrogel\u2010based triboelectric nanogenerator (PD\u2010TENG) is developed as a self\u2010powered wearable sensing platform for national fitness motion monitoring and intelligent evaluation. The device adopts a contact\u2013separation configuration with pPTFE and nylon as the triboelectric pair and PD hydrogel as the flexible conductive electrode. Benefiting from the synergistic coupling of polymer chains, ionic species, and dynamic intermolecular interactions, the hydrogel exhibits favorable flexibility, mechanical compliance, and interfacial adaptability. The optimized PD\u2010TENG delivers an open\u2010circuit voltage (\n                    <jats:italic>V<\/jats:italic>\n                    <jats:sub>OC<\/jats:sub>\n                    ) of 876\u2009V, a short\u2010circuit current (\n                    <jats:italic>I<\/jats:italic>\n                    <jats:sub>SC<\/jats:sub>\n                    ) of 40\u2009\u03bcA, a transferred charge (\n                    <jats:italic>Q<\/jats:italic>\n                    <jats:sub>SC<\/jats:sub>\n                    ) of 260\u2009nC, and a maximum output power of 598\u2009\u03bcW. It also maintains stable electrical performance under varying frequencies, separation distances, temperature, humidity, and external force. As a wearable sensor, it enables joint\u2010angle monitoring and distinguishes walking, running, and jumping, demonstrating promising potential for intelligent motion recognition and scoring.\n
