Cross-dimensional Shape-changing Architected Material from Rigid Planar Sheets

Stella Shen

All programmable shape-changing materials aim for a set of functional shapes. Nevertheless, central to the functionality of various natural and artificial systems are not only the final shapes, but also the pathways to the shapes, such as protein folding and insect wing deployment. Combining ortho-planar mechanisms, rotating polygon patterns and lamina emergent mechanism, we design a new class of architected material that can undergo cross-dimensional shape changes through multiple pathways in response to external loading. This material unlocks additional degrees of freedom that are inaccessible to conventional architected materials with the embedded mobility in it solid edges. Given the underlying mechanism are scalable and applicable across a wide range of materials, this study opens routes towards adaptive machines, multifunctional robotic materials, and physically intelligent systems.
