Source data for the publication: Metachronal micro‑Cilia for On-Chip Integrated Pumps and Climbing Robots

This data set contains the source data of the publication: Zhang, S., Cui, Z., Wang, Y. & Toonder, J.M.J. den (2021). Metachronal micro-cilia for on-chip integrated pumps and climbing robots. ACS Appl. Mater. Interfaces. DOI: https://doi.org/10.1021/acsami.1c03009. This paper demonstrates a simple method to realize metachronal microscopic magnetic artificial cilia (microMAC) through control over the paramagnetic particle distribution within the microMAC based on their tendency to align with an applied magnetic field. Actuated by a 2D rotating uniform magnetic field, the metachronal microMAC enable strong microfluidic pumping and soft robot locomotion. The metachronal micro MAC induce twice the pumping efficiency and 3 times the locomotion speed of synchronously moving microMAC. The ciliated soft robots show an unprecedented slope climbing ability and they display strong cargo-carrying capacity in both dry and wet conditions. The data are experimentally obtained with methods described in the publication.
