Abstract
An apparatus for forming a plurality of microdroplets from a droplet includes a substrate, a dielectric layer on the substrate and having a plurality of hydrophilic surface regions spaced apart from each other by a hydrophobic surface, and a plurality of electrodes covered by the dielectric layer. The electrodes are configured to form an electric field across the droplet in response to voltages provided by a control circuit to move the droplet across the dielectric layer in a lateral direction while leaving portions of the droplet on the hydrophilic surface regions to form the plurality of microdroplets on the hydrophilic surface regions.
