“Liquid crystal elastomers, as materials that integrate the mechanical properties of liquid crystal phases and polymers, exhibit strong autonomous deformation capabilities and have attracted much attention in the fields of flexible electronics, optical devices, and biomedical technology. Experts have achieved complex deformation patterns and functional characteristics by synchronously constructing the orientation and geometric structure of liquid crystal elastomers. By combining mechanical metamaterials, its application fields have been further expanded. The application of 3D printing technology has further promoted the construction of artificial ordered structures, laying the foundation for improving material properties.”
