基于三维可变换模块化kirigami的可编程结构材料
Three-dimensional transformable modular kirigami based programmable architected materials
摘要：
超材料从设计的建筑结构中获得了前所未有的特性。然而，它们通常由单个重复的构建块构造而成，该构建块表现出具有单自由度的单调形状变化，从而导致特定的空间形式和有限的可重构性。在这里，我们介绍了一个可变换的三维模块kirigami与多个自由度，可以重新配置成多功能的不同的子积木。因此，这些构建块的组合和空间模块化组装可以产生大量具有不同结构和独特性质的可重构结构材料，包括具有分叉状态的可重构一维周期性柱状材料，具有手性相变的二维晶格状结构材料，以及具有可编程变形模式的长程序的3D准周期性但无挫折的多层结构材料。我们的策略开辟了一条途径，设计一类新的模块化可重构超材料，可重新编程和可重复使用的潜在多功能建筑，声子，机械和机器人应用。
英文摘要：
Metamaterials achieve unprecedented properties from designed architected structures. However, they are often constructed from a single repeating building block that exhibits monotonic shape changes with single degree of freedom, thereby leading to specific spatial forms and limited reconfigurability. Here we introduce a transformable three-dimensional modular kirigami with multiple degrees of freedom that could reconfigure into versatile distinct daughter building blocks. Consequently, the combinatorial and spatial modular assembly of these building blocks could create a wealth of reconfigurable architected materials with diverse structures and unique properties, including reconfigurable 1D periodic column-like materials with bifurcated states, 2D lattice-like architected materials with phase transition of chirality, as well as 3D quasiperiodic yet frustration-free multilayered architected materials in a long-range order with programmable deformation modes. Our strategy opens an avenue to design a new class of modular reconfigurable metamaterials that are reprogrammable and reusable for potential multifunctionality in architectural, phononic, mechanical, and robotic applications.
