Abstract
A dynamically configurable electrode includes a first planar electrode and a planar array of pixels in a different plane, wherein a polarizable liquid medium (including electrolyte solutions) is to reside in the gap between electrodes. The pixels are individually addressable by a time-varying voltage, and adjacent pixels receive, at any instant in time, either the same voltage waveform or a different voltage waveform. Adjacent pixels receiving different voltage waveforms generate corresponding movement of dipolar entities, including dipolar particles, ions, or dipolar molecules in the polarizable liquid medium between the electrodes, which can in turn generate fluid flow and movement of particles suspended in the fluid along the planar array surface.
