Human skin sensing of mechanical stimuli originates from transduction mechanoreceptors that converts external forces into electrical signals. Although imitating the spatial distribution those can enable developments electronic skins capable decoupled normal/shear and strains, it remains elusive. We report a three-dimensionally (3D) architected (denoted as 3DAE-Skin) with force strain components arranged in 3D layout mimics Merkel cells Ruffini endings human skin. This 3DAE-Skin shows excellent performances normal force, shear enables development tactile system for simultaneous modulus/curvature measurements an object through touch. Demonstrations include rapid modulus fruits, bread, cake various shapes degrees freshness.

Abstract Transition metal carbides/nitrides (MXenes) demonstrate a massive potential in constructing lightweight, multifunctional wearable electromagnetic interference (EMI) shields for application various fields. Nevertheless, it remains challenging to develop facile, scalable approach prepare the MXene‐based macrostructures characterized by low density, thickness, high mechanical flexibility, and EMI SE at same time. Herein, ultrathin MXene/reduced graphene oxide (rGO)/Ag foams with porifera‐inspired hierarchically porous microstructure are prepared combining Zn 2+ diffusion induction hard template methods. The hierarchical porosity, which includes mesoporous skeleton microporous MXene network within skeleton, not only exerts regulatory effect on stress distribution during compression, making rubber‐like resistant wrinkling but also provides more channels multiple reflections of waves. Due interaction between Ag nanosheets, MXene/rGO, structure, is possible produce an outstanding shielding performance specific surface effectiveness reaching 109152.4 dB cm 2 g −1 . Furthermore, exhibit multifunctionalities, such as transverse Joule heating, longitudinal heat insulation, self‐cleaning, fire resistance, motion detection.
