Abstract
Methods and devices are provided for moving a droplet on an elongated track formed on a patterned surface using vibration. The elongated track includes a plurality of patterned transverse arcuate regions such that 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 transverse arcuate regions.
