ABSTRACT Conductive hydrogels hold significant promise in the fields of flexible electronics and smart sensing applications owing to their outstanding stretchability electrical conductivity. In this study, a dual‐network hydrogel based on polyacrylamide (PAAM) sodium alginate (SA) networks was constructed fabricate highly sensitive strain sensors. Carbon nanotubes (CNTs) were incorporated into system, polypyrrole (PPy) nanoparticles synthesized using SA as soft template. During preparing process, ultrasonic oscillation employed facilitate uniform distribution PPy matrix, then CNTs–PPy conductive pathway formed, thereby enhancing conductivity sensitivity hydrogel. The prepared PAAM–SA–CNTs–PPy exhibits high (4.84 S/m), superior mechanical properties (including tensile strength 683.5 kPa at 812%), toughness, good self‐healing, adhesion properties. assembled sensors demonstrate capability, wide measurement range (the gauge factor 2.67 for 0%–400% 5.25 400%–800% strain), rapid response times (126 ms), stability. developed hydrogel‐based sensor has potential be excellent candidates wearable devices monitoring human movements.
