Abstract

ABSTRACT Functional skins represent a transformative platform for diverse applications, yet their highly conformal deployment and maintenance remain challenging on substrates with arbitrary geometries, complex microstructures and dynamic deformation. Herein, we present a material‐form shift for functional skin fabrication, utilizing spray‐deposited polyacrylic acid/polyethyleneimine (PAA/PEI) lyophilized hydrogel powders embedded with functional components. Upon rehydration, these powders instantaneously coalesce into conformal hydrogel skins (
