Source data for the publication: Curved Surfaces Induce Metachronal Motion of Microscopic Magnetic Cilia

This data set contains the source data of the publication: Cui, Z., Islam, T. ul, Wang, Y. & Toonder, J.M.J. den (2024). Curved surfaces induce metachronal motion of microscopic magnetic cilia. ACS Appl. Mater. Interfaces. https://doi.org/10.1021/acsami.4c06884. In this paper, we present a novel elegant method that induces metachronal motion of arrays of identical microscopic magnetic artificial cilia by applying a simple rotating uniform magnetic field. The key idea of our method is to place arrays of cilia on surfaces with a specially designed curvature. This results in consecutive cilia experiencing different magnetic field directions at each point in time, inducing a phase lag in their motion, thereby causing collective wave-like motion. We characterize the local flow patterns generated by the motion of the cilia, revealing the formation of vortical patterns. The data are experimentally obtained with methods described in the publication.

本数据集包含下述发表论文的源数据：Cui, Z., Islam, T. ul, Wang, Y. 与 Toonder, J.M.J. den (2024). 《曲面诱导微型磁性纤毛的异时运动（metachronal motion）》, 《ACS应用材料与界面（ACS Appl. Mater. Interfaces）》, https://doi.org/10.1021/acsami.4c06884. 在本研究中，我们提出了一种新颖精妙的方法，通过施加简易的旋转均匀磁场，即可驱动完全一致的微型磁性人工纤毛阵列产生异时运动（metachronal motion）。该方法的核心思路是将纤毛阵列放置于具有特殊设计曲率的表面之上。这会使得相邻纤毛在每一时刻受到不同方向的磁场作用，进而在其运动过程中产生相位滞后，最终引发集体性的波状运动。我们对纤毛运动所产生的局部流场模式进行了表征分析，揭示了涡旋流场结构的形成。本数据集的实验数据均通过该论文中所述的实验方法获取。
