摘要

The growing interest in mimicry of biological skins greatly promotes the birthof high-performance artificial skins. Chameleon skins can actively transformenvironmental information into bioelectrical and color-change signals simultaneouslythrough manipulating ion transduction and photonic nanostructures.Here, inspired by chameleon skins, a novel biomimetic chromotropicphotonic-ionic skin (PI-skin) capable of outputting synergistic electrical andoptical signals under strain with robust adhesion, stability, and resilience isingeniously constructed. The PI-skin exhibits sensitive structural color changesynchronized with electrical response via adjusting the lattice spacing of thephotonic crystal (mechanochromic sensitivity: 1.89 nm per , Δλ > 150 nm).Notably, the polyzwitterionic network provides abundant electrostatic interactions,endowing the PI-skin with excellent adhesion, environmental tolerance,and outstanding mechanical stability (>10 000 continuous cycles). Meanwhile,the high loading of ionic liquid (IL) weakens the electrostatic interactionbetween the polyzwitterionic molecular chains, leading to high resilience.The PI-skin is finally applied to construct a visually interactive wearabledevice, realizing precise human motion monitoring, remote communication,and visual localization of pressure distribution. This work not only expandsdesign ideas for the construction of advanced biomimetic I-skins but also providesa general optical platform for high-level visual interactive devices andsmart wearable electronics.
