Hydrogels can change their size upon swelling. The swelling ratio is the same for all directions in stress-free state. Dielectric elastomers reduce thickness and expand area an electric field. Similarly, expansion plane also different directions. This isotropic shape effect limits function of these soft materials certain circumstances. To address this issue, recent works have shown that incorporation fibers into polymer matrix induce anisotropic response external stimulus. In work, we develop multi-field coupling models both fiber-reinforced hydrogels dielectric elastomers. For former, free energy caused by stretching chains mixing solvents networks. Fickian-type law adopted solvent diffusion. density latter consists a mechanical part, considering deformation fibers, polarization component. Gauss’s to obtain distribution are then implemented finite element analysis. We consider stimulus-responsiveness bilayer strips with active layer passive layer. Without bend contrast, changes helix shapes, which be further tuned changing fibers. work provides efficient design tool self-folding structures based on stimulus-responsive polymers.

Inchworm‐like robots have been increasingly investigated in recent years. However, most studies focused on one or several locomotion modes, lacking terms of inverted climbing, movement with a heavy load, and climbing vertical plane. Herein, an inchworm‐like soft robot is actuated multimodal using acrylic stick‐constrained dielectric elastomer actuator (ASCDEA). By assembling the ASCDEA flexible support frame, saddle‐like shape body designed to provide deformation ability for robot. This design enables move under load. Two electroadhesion actuators are implement anchoring action. Additionally, coordination control strategy developed synchronize locomotion. Experimental results confirm that can at maximum velocity 39.55 mm s −1 (0.53 length ) Moreover, capable locomotion, including horizontal crawling, turning rapid The navigate through confined tunnel while carrying payload, cross gap, circumvent obstacles, particularly robust owing its compliance.
