Source data for the publication: Miniaturized metachronal magnetic artificial cilia

This data set contains the source data of the publication: Cui, Z., Wang, Y., Zhang, S., Wang, T. & Toonder, J.M.J. den (2023). Self-cleaning surfaces realized by biologically  sized magnetic artificial cilia. PNAS 2023, Vol. 120, No. 35, e2304519120. https://doi.org/10.1073/pnas.2304519120. In this study, we introduce a concept that generates metachronal motion of magnetic artificial cilia (MAC), even though the MAC are all identical, and the applied external magnetic field is uniform. This is achieved by integrating a paramagnetic substructure in the substrate underneath the MAC. Uniquely, we can create both symplectic and antiplectic metachrony by changing the relative positions of MAC and substructure. We demonstrate the flow generation of the two metachronal motions in both high and low Reynolds number conditions. 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.、Wang, Y.、Zhang, S.、Wang, T. 与 den Toonder, J.M.J. 于2023年发表的《基于生物尺度磁性人工纤毛的自清洁表面》。该论文发表于《美国国家科学院院刊》（PNAS）2023年第120卷第35期，文章编号为e2304519120，DOI链接为https://doi.org/10.1073/pnas.2304519120。本研究提出了一种可使磁性人工纤毛（magnetic artificial cilia, MAC）产生异相运动的概念：即便所有MAC均完全一致，且施加的外部磁场为均匀磁场，仍可实现该运动。这一效果通过在MAC下方的基底中集成顺磁子结构得以实现。独特之处在于，通过调整MAC与子结构的相对位置，我们可生成同向异相与反向异相两种异相运动模式。我们分别在高雷诺数与低雷诺数条件下，验证了两种异相运动的流体生成效果。本数据集的实验数据均按照该论文中所述的实验方法获取。
