我们研究了 Tachi-Miura 多面体 (TMP) 镶嵌的可重构性和可调性，TMP 是一种由风箱状晶胞组成的基于折纸的细胞结构。与传统材料相比，基于晶格的三维机械超材料由于其优越且独特的机械性能，最近引起了极大的科学兴趣。然而，从这些超材料中实现可调谐性和可重构性通常具有挑战性，因为它们的几何形状和功能往往是在设计和制造阶段预先确定的。在这里，我们利用 TMP 高度通用的相变和镶嵌功能来设计具有可调机械性能的可重构超材料架构。热处理的理论分析和实验发现超材料在弹性变形范围内制造后具有广泛的原位可调性，特别是有效密度、杨氏模量和泊松比的数量级变化。我们还见证了有效密度和刚度之间的反比关系的相当独特的行为。该机械平台为设计能够主动适应各种外部环境的超材料铺平了道路。
We investigate the reconfigurability and tunability of the tessellation of Tachi-Miura Polyhedron (TMP), an origami-based cellular structure composed of bellows-like unit cells. Lattice-based three-dimensional mechanical metamaterials have recently received significant scientific interest due to their superior and unique mechanical performance compared to conventional materials. However, it is often challenging to achieve tunability and reconfigurability from these metamaterials, since their geometry and functionality tend to be pre-determined in the design and fabrication stage. Here, we utilize TMP's highly versatile phase-transforming and tessellating capabilities to design reconfigurable metamaterial architecture with tunable mechanical properties. The theoretical analyses and experiments with heat processing discover the wide range of the in-situ tunability of the metamaterial – specifically orders of magnitude change in effective density, Young's modulus, and Poisson's ratio – after its fabrication within the elastic deformation regime. We also witness a rather unique behavior of the inverse correlation between effective density and stiffness. This mechanical platform paves the way to design the metamaterial that can actively adapt to various external environments.
