In contrast to conventional hard actuators, soft actuators offer many vivid advantages, such
as improved flexibility, adaptability, and reconfigurability, which are intrinsic to living …

The influx and efflux of water in biological structures actuates reversible deformation and
recovery processes that are crucial for mechanical functions in plants and animals. These …

By combining the two basic deformation mechanisms for auxetic open-cell metamaterials, re-
entrant angle and chirality, new hybrid chiral mechanical metamaterials are designed and …

Ever-increasing requirements for structural performance drive the research and the
development of stronger, tougher and lighter materials. Specific microstructures …

Plants exhibit a variety of reversible motions, from the slow opening of pine cones to the
impulsive closing of Venus flytrap leaves. These motions are achieved without muscles and …

Inspired by the physics behind the rapid plant movements and the rich topologies in origami
folding, this research creates a unique class of multi-functional adaptive structure through …

For the first time, the concept of amplifying chirality‐induced auxetic effect via elevating
internal rotation efficiency is proposed. Based on this concept, new chiral cellular solids with …

The spirally arranged stems of the spikemoss Selaginella lepidophylla, an ancient
resurrection plant, compactly curl into a nest-ball shape upon dehydration. Due to its spiral …

New hybrid auxetic chiral mechanical metamaterial are designed and fabricated via multi‐
material 3D printing. Due to the chirality‐induced rotation, the material have unique …

Fins from ray-finned fishes do not contain muscles, yet fish can change the shape of their
fins with high precision and speed, while producing large hydrodynamic forces without …
