4D Printing of Chiral Mechanical Metamaterials with Modular Programmability using Shape Memory Polymer

Yi Wu, Ying Han, Zhuxuan Wei, Yu Xie et autres

Abstract The rational design of mechanical metamaterials endows them with unusual properties inaccessible by conventional materials. In this study, compression–twist coupling building blocks with embedded chirality are fabricated by multimaterial 4D printing of shape memory polymers. Each chiral unit can be programmed …

Shape Morphing of 3D Printed Liquid Crystal Elastomer Structures with Precuts

Liqian Wang, Zhuxuan Wei, Zengting Xu, Zi Liang Wu et autres

Liquid crystal elastomer (LCE) is a typical thermally responsive soft material, which is an ideal candidate for fabricating programmable shape changing structures. The anisotropic shape changes of LCEs caused by the mesogen reorientation are inherently different from those of other stimulus-responsive soft …

Programming Soft Shape-Morphing Systems by Harnessing Strain Mismatch and Snap-Through Bistability: A Review

Yi Wu, Gang Guo, Zhuxuan Wei, Jin Qian

Multi-modal and controllable shape-morphing constitutes the cornerstone of the functionalization of soft actuators/robots. Involving heterogeneity through material layout is a widely used strategy to generate internal mismatches in active morphing structures. Once triggered by external stimuli, the entire structure undergoes cooperative deformation …
