Abstract Ionic skins with perception capabilities similar to natural skin are compelling candidates for monitoring physiological signals. The green leather containing rich interspaces among dense collagen fibers is a promising skeleton load soft ionic gels constructing skins. However, such still plagued by weak interior combination of the two components and inhomogeneous conductivity. Herein, multiscale interfacial designed ionogel/leather uniform conductivity prepared incorporating liquid (IL) into polyvinyl alcohol (PVA)‐polyacrylamide (PAM)/Leather composite construct strong bonding continuous ionically conductive paths. induces volume shrinkage accompanied entanglements PVA‐PAM polymer chains fibers, together polymer‐rich domains associated hydrogen bonds various functional groups, contributing tight PVA‐PAM/IL ionogel matrix tough skeleton. force between increased 2.5 times. Such integration confers resultant applications in wearable strain, temperature, respiration sensing. This study enhances overall performance expands its multiple
