Hydrogels have been attracting increasing attention for application in wearable electronics, due to their intrinsic biomimetic features, highly tunable chemical-physical properties (mechanical, electrical, etc.), and excellent biocompatibility. Among many proposed varieties of hydrogels, conductive polymer-based hydrogels (CPHs) emerged as a promising candidate future sensor designs, with capability realizing desired features using different tuning strategies ranging from molecular design (with low length scale 10-10 m) micro-structural configuration (up 10-2 m). However, considerable challenges remain be overcome, such the limited strain sensing range mechanical strength, signal loss/instability caused by swelling/deswelling, significant hysteresis signals, de-hydration induced malfunctions, surface/interfacial failure during manufacturing/processing. This review aims offer targeted scan recent advancements CPH based technology, establishment dedicated structure-property relationships lab advanced manufacturing routes potential scale-up production. The CPHs sensors is also explored, suggested new research avenues prospects included.

Abstract Stretchable conductors with the combination of high elasticity and electric conductivity have long been pursued in soft electronics. Liquid metals (LMs), whose mechanical properties match well elastomeric matrix, successfully applied robotics, electronic skins wearable devices. But it remains challenging to develop conductive composite elastomers LMs reversible adhesion self‐healing. Herein, EGaIn droplets are uniformly dispersed into elastomer, which contain dynamic disulfide endow elastomer thermal processability, recyclability, wet adhesion, With content ≥40 vol.%, resultant shows 1.3 × 104 S m −1 , self‐healing 8.0 h, strength up 670 kPa after curing for 2.0 h. When serving as adhesive, can easily adhere metal electrode light LED even when stretched 50%. self‐adhesive bioelectrode, also detect human electromyography signals. Thus, not only may this study provide a new platform designing self‐adhesive, self‐healing, liquid metals, but their promise facileness building damage‐endurable electronics applying human–machine interfaces.
