Abstract
Methods and devices for moving a droplet on an elongated track on a textured surface using vibration. The elongated track on the textured surface includes a plurality of transverse arcuate projections such that a droplet on the surface is in the Fakir state and when the surface is vibrated the droplet is urged along the track as a result of an imbalance in the adhesion of a front portion of the droplet and a back portion of the droplet to the textured surface.
