Abstract Inspired from helical structures in nature, liquid crystal elastomer (LCE) fiber actuators are developed for soft robotics and smart wearables. However, the facile development of robust LCE yarn remains challenging due to lightly cross‐linked networks with inherently poor mechanical properties. Here, bionic actuator is constructed through integrating shape‐morphing as actuation phase highly ordered orientation biomass bacterial cellulose (BC) macrofibers reinforcement by a twisting two‐step cross‐linking strategy. Thanks 3D nanofiber network inside BC biomimetic structure, strength (43.9 MPa) creep phenomenon resulted have been significantly improved, which obviously better than reported (1.4–30.8 MPa). The designed LCE/BC demonstrate high work capacity (304.1 J kg −1 ) reliable reusability. As proof‐of‐concept, this constructs micro rolling device customizable speed, gripper grasping moving heavy objects passive motor speed 7.7 rad s . findings expected provide insights into high‐performance durable engineering strategies.

Bio-inspiration offers researchers innovative perspectives and methodologies, stimulating the advancement of high-performance, high-durability, added-value materials, structures, products. Inspired by lightweight, high-strength, highly stable glass sponges (GSs), five types sponge lattice structures (GSLSs) were successfully designed manufactured selective laser melting (SLM) with Ti6Al4V. By conducting a comparative analysis unit cell design manufacturing deviations, we assess their impact on compressive properties GSLSs. Notably, original GSLS circle-/grid-like heterogeneous geometries exhibits outstanding overall compression performance, including stability, stress dispersion unique cell-by-cell layer-by-layer fracture mechanisms among GSLSs, which are attributable to reinforced diagonal struts cells. Hence, three strategies for optimization proposed. These discoveries guide future (LSs) offer potential applications GSLSs in aerospace, biomedicine, automobiles, architecture, wearable
