Summary

• What is new: A magnetic-responsive surface that enables manipulation of liquids and solids with multiple degrees of freedom, inspired by natural systems.
• Why this is important: The challenge in designing functional surfaces for small-scale liquid/solid manipulation that are flexible, tunable, and capable of multimodal operations.
• What the research proposes: A surface with curvature pillars that can manipulate liquids and solids under static and dynamic magnetic fields, thanks to its innovative design mimicking natural structures.
• Results: Demonstrated effective liquid operations like anti-gravity climbing and mixing, and 3-DOF solid transportation using magnetic-driven movement of the surface’s pillars.
