An ultralight, multilayer anisotropic tactile sensor—an artificial Pacinian corpuscle—exhibits ultrahigh tangential sensitivity (1022 kPa−1) and spatiotemporal sensing. It discriminates static, sliding, and rolling contacts, detects incipient stick–slip via high‑frequency signatures, and enhances robotic touch (100%/98.18% accuracy for active/passive ...

Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

A 3D‐printed anisotropic channel evaporator integrates directional geometry with aligned titanium oxide, boron nitride, and chitosan networks to coordinate photon absorption, heat localization, and water transport. Phonon‐guided thermal pathways and interfacial water structuring enable ultrahigh evaporation rates and long‐term salt‐resistant solar ...

This study introduces an innovative interpenetrating layered structure, comprising alternating aramid nanofiber (ANF) layers and MXene layers, fabricated through a directional freeze–thaw intercalation–gel‐film formation strategy. Unlike traditional homogeneous layered films, this unique layered structure features mutually embedded conductive and ...

Sulfonated cellulose acetate (SCA) nanofiber membrane with zincophilic‐hydrophobic property is constructed on the surface of the Zn anode by the electrospinning technique to tune the 3D deposition behavior of Zn2+ by chemisorption and micro‐sized physical structure. The negatively‐charged groups of SCA nanofiber membrane form an electrostatic repulsion
