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.

(2023). 通过生物尺度磁性人工纤毛（magnetic artificial cilia, MAC）实现的自清洁表面. 《美国国家科学院院刊》（PNAS）2023年，第120卷，第35期，e2304519120. https://doi.org/10.1073/pnas.2304519120. 本研究提出一种概念，可在磁性人工纤毛（magnetic artificial cilia, MAC）均一且施加的外部磁场均匀的条件下，驱动MAC产生异时运动（metachronal motion）。这一效果通过在MAC下方的基底中集成顺磁子结构实现。独特之处在于，通过改变MAC与子结构的相对位置，可同时实现symplectic节律（symplectic metachrony）和antiplectic节律（antiplectic metachrony）。我们展示了这两种异时运动在高、低雷诺数条件下的流动生成能力。数据集通过该出版物中描述的方法实验获得。
