Abstract Conductive polymer hydrogels (CPHs) are gaining considerable attention in developing wearable electronics due to their unique combination of high conductivity and softness. However, the absence interactions, incompatibility between hydrophobic conductive polymers (CPs) hydrophilic networks gives rise inadequate bonding CPs hydrogel matrices, thereby significantly impairing mechanical electrical properties CPHs constraining utility electronic sensors. Therefore, endow with good performance, it is necessary ensure a stable robust network CPs. Encouragingly, recent research has demonstrated that incorporating supramolecular interactions into enhances interaction, improving overall CPH performance. comprehensive review focusing on (SCPH) for sensing applications currently lacking. This provides summary typical strategies employed development high‐performance elucidates SCPHs closely associated Moreover, discusses fabrication methods classification SCPH sensors, while also exploring latest application scenarios Finally, challenges sensors offers suggestions future advancements.
