Bioinspired Super‐Robust Conductive Hydrogels for Machine Learning‐Assisted Tactile Perception System

Abstract Conductive hydrogels have attracted significant attention due to exceptional flexibility, electrochemical property, and biocompatibility. However, the low mechanical strength can compromise their stability under high stress, making the material susceptible to fracture in complex or harsh environments. Achieving a balance between conductivity and mechanical robustness remains a critical challenge. In this study, super‐robust conductive hydrogels were designed and developed with highly oriented structures and densified networks, by employing techniques such as stretch‐drying‐induced directional assembly, salting‐out, and ionic crosslinking. The hydrogels showed remarkable mechanical property (tensile…
