Abstract As a soft material with biocompatibility and stimulation response, ionic conductive hydrogel‐based wearable strain sensors show great potential across wide spectrum of engineering disciplines, but their mechanical toughness is limited in practical applications. In this study, freeze‐thawing techniques were utilized to fabricate double‐network hydrogels poly(vinyl alcohol)/polyacrylamide (PVA/PAM) both covalent physical cross‐linking networks. These demonstrate excellent performance, an elongation at break 2253% tensile strength 268.2 kPa. Simultaneously, they also display high sensitivity (Gage factor, GF = 2.32 0%–200% strain), achieve rapid response time 368 ms without the addition extra fillers or ions, stable signal transmission even after multiple cycles, fast human motion detection.
