Conductive hydrogels have been extensively studied as flexible sensing materials. However, conventional conductive often exhibit low sensitivity due to the limited incorporation of electronic fillers when directly mixed with polymer components before gelatinization. To address this issue, we developed a strategy establish carbon nanotube network within hydrogel by freeze-drying dispersion produce an aerogel and then encapsulating By using in situ formed, poly(vinyl alcohol) (PVA) reinforced Al3+ cross-linked poly(acrylic acid) (PAA) matrix, composite achieved excellent performance, including high (gauge factor = 29.34), broad working range 0–1000%, ultralow detection limit 0.1%. Additionally, demonstrated mechanical properties, adhesion, self-healing, bacteriostatic properties. Moreover, hydrogel-based sensor is capable monitoring human health various activities. The also exhibits good water retention adaptability extreme temperatures soaking 50% glycerol aqueous solution for 4 h. This work provides approach fabricating high-performance wearable devices.
