当微结构放置在液滴上时，由于毛细管力，该结构被定位并保持在特定位置。利用这种现象，液滴上的二维排列得到了广泛的发展。在这项研究中，我们通过在液滴上放置两个圆形板来制造三维结构（棱柱形状）。该论文通过实验和数值解释了定位的动态。通过实验和模拟，我们发现旋转定位是由表面张力决定的，并且两个板由内部压力和表面张力支撑。通过改变棱镜的体积可以轻松调整棱镜的顶角。如论文末尾所述，通过沉积有机聚对二甲苯膜来封装由一滴硅油和两个透明圆形 SU-8 板组成的棱镜。液体形状固定，形成不蒸发、不变形的棱柱体，体积小于1mm 3 。
When a microstructure is placed on a droplet, the structure is positioned and remains at a particular position due to capillary forces. By using this phenomenon, two-dimensional arrangements on droplets have been widely developed. In this study, we fabricate a three-dimensional structure (prism shape) by placing two circular plates on a droplet. The paper explains the dynamics of the positioning both experimentally and numerically. Through experiment and simulation, we found that the rotational positioning is determined by surface tension and the two plates are supported by internal pressure and surface tension. The apex angle of the prism can be easily tuned by changing its volume. As described at the end of the paper, a prism composed of a droplet of silicone oil and two transparent circular SU-8 plates is encapsulated by depositing an organic Parylene membrane. The shape of the liquid is fixed, and a non-evaporative and non-deformable prism is formed with a volume of less than 1 mm 3.
