Inside Front Cover: Elastic Nanoparticle-Reinforced, Conductive Structural Color Hydrogel With Super Stretchability, Self-Adhesion, Self-Healing as Electrical/Optical Dual-Responsive Visual Electronic Skins (EXP2 2/2025)

Abstract

We present a novel conductive structural color hydrogel, in which highly charged elastic nanoparticles are elaborately used as structural color building blocks to enhance interfacial compatibility between the hydrogel network and nanoparticles, thereby enabling effective energy dissipation. The obtained hydrogel can achieve excellent mechanical robustness, self-adhesiveness, self-healing properties, as well as synchronous electronic and visual signal monitoring.
