Kirigami‐Inspired Three‐Dimensional Metamaterials with Programmable Isotropic and Orthotropic Thermal Expansion

Mechanical metamaterials with specifically designed cells can provide unusual thermal expansion properties for diverse applications. Limited by very few available cell topologies and complicated non-linear structural deformation, most existing only achieve orthogonally isotropic negative/zero/positive (NTE/ZTE/PTE) within a mild range, especially the 3D ones. Here, based on one-degree-of-freedom kirigami polyhedrons proposed kinematic design strategy, family of orthotropic capable programmable NTE, PTE, even ZTE over ultra-wide range is developed. Incorporating bi-material strips as creases polyhedrons, NTE PTE coefficients (CTEs) ranging from -2354.3 to 3006.7 ppm/°C are programmed theoretical model. Meanwhile, constructed either homogeneous tessellation or hybrid cells. Furthermore, allowing distinct geometric parameters in three orthogonal directions while preserving motion, metamaterials, which each be assigned an independently ZTE, also achieved. This study paves novel pathway development potential applications space optical systems, MEMS, so on.
