Reconfigurability-Encoded Hierarchical Rectifiers for Versatile 3D Liquid Manipulation.

ABSTRACT: Manipulating small-volume liquids is crucial in natural processes and industrial applications. However, most liquid manipulation technologies involve complex energy inputs or non-adjustable wetting gradient surfaces. Here, a simple and adjustable 3D liquid manipulation paradigm is reported to control liquid behaviors by coupling liquid-air-solid interfacial energy with programmable magnetic fields. This paradigm centers around a hierarchical rectifier with magnetized microratchets, using Laplace pressure asymmetry to enable multimodal directional steering of various surface tension liquids (23-72 mN m^-1). The scale-dependent effect in microratchet design shows its superiority in handling small-volume liquids across three orders of magnitude (10⁰-10³ µL). Un
