Ionically conductive hydrogels with high mechanical strength for wearable sensors

(6 wt%) hydrogel exhibits a wide detection range, fast response time, negligible hysteresis, and high sensitivity (GF = 4.56 at 400-600% strain), enabling accurate capture of large-scale human motions as well as movements such as mouth opening and swallowing. This study demonstrates a multifunctional, high-performance conductive hydrogel, showing promise for applications in wearable health monitoring.
