论文摘要
日本切割艺术的基里加米（Kirigami）最近实现了可拉伸的机械超材料的设计，可以通过将定期切割阵列嵌入弹性纸中来轻松实现。在这里，我们利用Kirigami原理来设计可以在加压时模仿目标形状的充气物。我们的系统包括嵌入非结构化弹性膜中的基里加米纸。首先，我们表明可以通过调整基里加米模式的几何参数来控制膨胀的形状。然后，通过应用简单的优化算法，我们确定了使Kirigami充气物能够在给定压力下转变为目标形状家族的最佳参数。此外，由于Kirigami的缝线性质，我们表明我们可以选择性地操纵单个单元的参数，以允许在不同尺度上复制特征，并最终使目标更准确地模仿目标。
Kirigami, the Japanese art of paper cutting, has recently enabled the design of stretchable mechanical metamaterials that can be easily realized by embedding arrays of periodic cuts into an elastic sheet. Here, we exploit kirigami principles to design inflatables that can mimic target shapes upon pressurization. Our system comprises a kirigami sheet embedded into an unstructured elastomeric membrane. First, we show that the inflated shape can be controlled by tuning the geometric parameters of the kirigami pattern. Then, by applying a simple optimization algorithm, we identify the best parameters that enable the kirigami inflatables to transform into a family of target shapes at a given pressure. Furthermore, thanks to the tessellated nature of the kirigami, we show that we can selectively manipulate the parameters of the single units to allow the reproduction of features at different scales and ultimately enable a more accurate mimicking of the target.
