提出了一种通过控制微粒上的褶皱来构建迷宫结构的新的自组织方法。自然界中发现的复杂的三维(3D)结构是由自下而上的自然过程自组织的。为了人工构建这些复杂的系统，已经开发了各种自下而上的制造方法，旨在将2D结构转换为3D结构，作为传统的自上而下光刻工艺的替代。我们提出了一种不同的自组织方法，在这种方法中，我们构建具有周期性和有序的微结构，但具有随机结构，如迷宫。为此，我们使用褶皱来变换平面曲面，以直接使用随机生成的脊线作为迷宫墙。高度规则的迷宫结构由多个具有定制设计的镶嵌组成，通过脊导引结构精确控制褶皱，类似于折纸中的折痕。该方法可广泛应用于多种不同长度尺度的材料系统。
A novel self-organization approach for constructing maze-like structures is presented by controlling wrinkling on a microparticle. Sophisticated three-dimensional (3D) structures found in nature are self-organized by bottom-up natural processes. To artificially construct these complex systems, various bottom-up fabrication methods, designed to transform 2D structures into 3D structures, have been developed as alternatives to conventional top-down lithography processes. We present a different self-organization approach, where we construct microstructures with periodic and ordered, but with random architecture, like mazes. For this purpose, we transformed planar surfaces using wrinkling to directly use randomly generated ridges as maze walls. Highly regular maze structures, consisting of several tessellations with customized designs, were fabricated by precisely controlling wrinkling with the ridge-guiding structure, analogous to the creases in origami. The method presented here could have widespread applications in various material systems with multiple length scales.
