Hierarchically Arranged Helical Fiber Actuators Derived from Commercial Cloth

The first hygroscopic tunable cloth actuator is realized via modification of commercial cloth template by a 3D nanoporous polymer hybrid. The nanoporous hybrid guarantees fast water diffusion and amplifies deformation. The cloth actuator achieves a large-scale size production, tunable motion, high tensile strength and mechanical flexibility with a breadth of utilities (e.g., electric generator and smart materials).
