Skin-Inspired Ultra-Tough Supramolecular Multifunctional Hydrogel Electronic Skin for Human–Machine Interaction

Abstract

HighlightsThe skin-inspired multifunctional ultra-tough electronic skin with tunable mechanical properties was developed by a physically cross-linking salting-freezing-thawing method.The hydrogel integrates transparency (>60%), super toughness (up to 13.96 MJ m−3), good antibacterial properties (E. coli and S. aureus), UV protection (Filtration: 80%–90%), high electrical conductivity (4.72 S m−1), anti-swelling and recyclability.As a human–machine interface, it can be used for complex underwater activities, information encryption/decryption and finger joint rehabilitation training.
