Multifunctional, Ultra‐Tough Organohydrogel E‐Skin Reinforced by Hierarchical Goatskin Fibers Skeleton for Energy Harvesting and Self‐Powered Monitoring

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(42)

Published: June 24, 2023

Abstract E‐skins based on conductive hydrogels are regarded as ideal candidates for sensing application. However, limited by the constructed materials and strategies, current have poor mechanical properties, single function, unsatisfactory conductivity, which seriously hinder their development Herein, natural goatskin with hierarchical 3D network structure weaved collagen fibers is used substrate material construction of ultra‐tough hydrogel through a “top‐down” strategy, in acrylic acid monomer first vacuum‐impregnated into interstices skeleton then polymerized situ to produce skin‐based unique wrapping structure. Based hydrogel, load‐carrying capacity, after loaded new multifunctional nanoscale‐conductive medium nanosilver particles (AgNPs) 1,3‐propanediol, goatskin‐derived organohydrogel S@HCP excellent self‐adhesion, transparency, ultraviolet shielding, antibacterial, biocompatibility, environmental stability, conductivity. Notably, stretchable S‐TENG assembled using can be perfectly suited real‐life applications including biomechanical energy harvesting, self‐powered tactile‐sensing, motion monitoring. It believed that, combining animal skin different functional materials, it possible reuse skin, “dead skin,” provides platform developing flexible e‐skin.
