Al3+-Crosslinked Transparent Ionic Conductive PAA-Lysine Hydrogels Toward Flexible High-Sensitivity Electrochemical Sensors
Flexible hydrogel sensors hold great promise in wearable electronics, smart healthcare, and human–machine interfaces, yet their practical applications are often hindered by poor mechanical robustness, insufficient low-temperature tolerance, lack of self-healing ability, and inferior biocompatibility. Herein, we present...
