More Information
Summary:A digital microfluidic device, comprising a bottom plate and a top plate. The bottom plate comprises a bottom electrode array comprising a plurality of digital microfluidic propulsion electrodes. The top plate comprises a segmented top electrode array comprising a plurality of separately voltage addressable top electrode segments. Each top electrode segment and at least two of the propulsion electrodes of the bottom electrode array form a zone within the device. A controller is operatively coupled to the top electrode array and to the bottom electrode array and is configured to provide propulsion voltages between the top plate segment and the bottom plate propulsion electrodes of at least one of the zones. The top plate and the bottom plate are provided in a spaced relationship defining a microfluidic region therebetween.
