From: Droplet-based mechanical transducers modulated by the symmetry of wettability patterns
a Scheme of the experimental setup. b Design principle of the wettability pattern. c The translational swarm behavior along x-axis realized using circle array. d The translational swarm behavior along y-axis realized using ellipse array. e The translational swarm behavior along z-axis realized using gourd array. f The tilting swarm behavior around x-axis realized using R-gourd array. g The tilting swarm behavior around y-axis realized using M-gourd array. h The rotational swarm behavior around z-axis realized using M-ellipse array.
