Microfabrication techniques electrode configuration

A DHT configuration on a planar surface is shown in Fig. 2 where droplets are actuated via electrowetting on a dielectric (EWOD) or dielectrophoresis (DEP). In both these actuation methods, electrodes are patterned onto a substrate using microfabrication techniques and then covered with a dielectric layer that also functions as a hydrophobic layer. If a voltage is applied to an electrode near the interface of a droplet, the...
