Ratchet Motion of a Droplet

We showed that the ratchet motions of a droplet were induced by very simple asymmetric guides [45]. Figure 16.7 shows a schematic drawing of the electrode causing the ratchet motions of a droplet.

The ratchet motion of a droplet was induced by electrochemical control of the wetting distributions on the surface [44]. Figure 16.9 shows the principles for the generation... 

When a droplet is deformed asymmetrically, the ratchet motions of the droplet can be induced as demonstrated on the vibrated gradient surface and on a saw-shaped electrode on which the wetting was changed by electrowetting [48].
