Liquid crystal elastomers (LCE) and magnetic soft materials are promising active in many emerging fields, such as robotics. Despite the high demand for developing that combine advantages of LCE actuation, lack independent programming nematic order magnetization a single material still hinders desired multi-responsiveness. In this study, ferromagnetic (magLCE) ink with is developed can be independently programmed to anisotropic, referred "dual anisotropy", via customized 3D-printing platform. The magLCE fabricated by dispersing microparticles matrix, platform created integrating magnet 3-DoF motion into an extrusion-based 3D printer. addition magLCEs also actuated heating sources (either environmental or photo-heating embedded microparticles) energy density tunable actuation temperature. A strip robot demonstrated enhanced adaptability complex environments (different terrains, temperatures) using multi-actuation strategy. has potential applications mechanical memory, multistable metastructure array remote writability stable memory.

Untethered soft robots have attracted growing attention due to their safe interaction with living organisms, good flexibility, and accurate remote control. However, the materials involved are often nonbiodegradable or derived from nonrenewable resources, leading serious environmental problems. Here, we report a biomass-based multistimuli-responsive actuator based on cuttlefish ink nanoparticles (CINPs), wood-derived cellulose nanofiber (CNF), bioderived polylactic acid (PLA). Taking advantage of photothermal conversion performance exceptionally hygroscopic sensitivity CINPs/CNF composite (CICC) layer opposite thermally induced deformation behavior between CICC PLA layer, exhibits reversible behaviors under near-infrared (NIR) light, humidity, temperature stimuli, respectively. By introducing patterned alignment structures combining them macroscopic reassembly strategy, diverse programmable shape-morphing 2D 3D such as letter-shape, coiling, self-folding, more sophisticated deformations been demonstrated. All these can be successfully predicted by finite element analysis (FEA) . Furthermore, this has further applied an untethered grasping robot, weightlifting climbing robot capable vertical pole. Such actuators consisting entirely biodegradable will offer sustainable future for robots.

Liquid crystal elastomer (LCE) is a typical thermally responsive soft material, which an ideal candidate for fabricating programmable shape changing structures. The anisotropic changes of LCEs caused by the mesogen reorientation are inherently different from those other stimulus-responsive materials, such as hydrogels and dielectric elastomers. In this paper, we first investigate bending behaviors bilayer with monodomain active layer polydomain passive layer. It shown that folding can be obtained aspect ratio. We further propose strategy to achieve complex activated LCE deformations through introducing precuts into printed structures, change degrees freedom morphing our design beyond ability based on materials. Our method provide far-reaching possibilities devices 3D actuators various functionalities.

In this paper, phenomenon described, self-oscillation mechanism revealed. The results indicate that varying parameters initial conditions, patterns emerge, namely, full mode, partial asynchronous mode. For strongly interacting systems, mode always prevails, while for weak interactions, adjustment velocities magnitude direction yields patterns.
