The hydrogel exhibits exceptional mechanical and electrical properties, including high tensile strength (91.2\u00a0kPa), extensibility (1210%), conductivity (178.8 S\u00a0m\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 200% strain), and long\u2010term durability, achieved through the synergistic effects of hydrogen bonding, dynamic Fe\n                    <jats:sup>3<\/jats:sup>\n                    \u207a coordination, and ionic conductivity. The sensor demonstrates precise and proportional resistance responses to various mechanical stimuli, such as bending, stretching, and tapping motions, enabling accurate detection of joint movements, including the fingers, wrist, and elbow. Furthermore, the hydrogel's fast response and low noise allow for reliable differentiation of motion speeds and the successful transmission of Morse code signals. The long\u2010term stability and cyclic durability of the sensor highlight its robustness for real\u2010time applications. These versatile hydrogels offer a promising platform for wearable electronics, gesture recognition, and human\u2010machine interfaces, paving the way for next\u2010generation interactive sensing technologies. Moreover, the preparation method ensures high reproducibility and scalability, making it suitable for large\u2010scale manufacturing.\n
