Abstract:
1. An apparatus comprising first and second electrodes, each having a surface, said surfaces being opposed and positioned to accommodate a fluid medium between said surfaces, wherein the fluid medium may contain a plurality of polarizable particles, wherein the first and the second electrodes are configured relative to one another so that an electric field is generated within an interface between said fluid medium and at least one of said first or second electrodes when an AC voltage is applied between the electrodes in the presence of said fluid medium, and wherein at least one of said first and second electrodes comprises a light-sensitive electrode capable of controlling the movement of the particles and/or the fluid medium in a direction substantially parallel to the electrode surface when an electric field is generated within said interface and the light-sensitive electrode is illuminated with a predetermined light pattern.
