Abstract
An apparatus and method fox micropumping is disclosed. The apparatus includes a virtual or physical microchannel and at least two hydrophobic electrode patches on a surface or two electrode patches disposed underneath a dielectric film proximate to the channel. Each of the electrode patches modifies a surface property between hydrophobic and hydrophilic states in response to an electrical potential applied between the liquid and the electrode, and the electrical potential is provided to digitize the liquid, drive the liquid segments, and mix different liquids.
