Dynamic interfacial interactions between the HAPAA and PANI hydrogels are favorable for self-healing; thus, the PANI network can enhance the mechanical and electronic properties of HAPAA hydrogel without compromising its self-healing performance.

A cephalopod-inspired mechanoluminescence material with skin-like self-healing and sensing properties was developed by the construction of a unique strain-dependent microcrack-structured conductive UV-shielding layer upon a self-healable supramolecular fluorescent elastomer with synergistic dynamic crosslinking network design.
