Kirigami需要切割一个平坦的薄片，通过内部瓷砖的协调旋转，使其从封闭、紧凑的配置转变为开放的部署结构。通过识别和推广使这种艺术形式成为可能的几何约束，我们提出了一种紧凑的可重构基里伽米图案的设计框架，它可以从封闭和紧凑的配置转变为符合任何规定目标形状的部署状态，然后收缩成不同的封闭和紧凑的配置。我们进一步建立了产生基里伽米模式和机制的条件，这些模式和机制是可重构和刚性部署的，允许我们通过零能量的部署状态族连接紧态。总之，我们的逆向设计框架为形状变形材料结构的创建提供了一条路径。
Kirigami involves cutting a flat, thin sheet that allows it to morph from a closed, compact configuration into an open deployed structure via coordinated rotations of the internal tiles. By recognizing and generalizing the geometric constraints that enable this art form, we propose a design framework for compact reconfigurable kirigami patterns, which can morph from a closed and compact configuration into a deployed state conforming to any prescribed target shape, and subsequently be contracted into a different closed and compact configuration. We further establish a condition for producing kirigami patterns and mechanisms which are reconfigurable and rigid deployable allowing us to connect the compact states via a zero-energy family of deployed states. All together, our inverse design framework lays out a path for the creation of shape-morphing material structures.
