Methods and apparatus implementing a technique for electrostatically transporting a particle (130) through a medium. In general, one implementation includes a substrate (130); a first insulation layer (120) formed on the substrate (130); a plurality of electrodes (105, 110, 115) arranged in a sequence on the insulation layer (120), where the electrodes (105, 110, 115) are divided into a plurality of groups and the electrodes are arranged by group; a second insulation layer (235) over at least one of the electrodes (105, 110, 115); and a phase-shift circuit (800) connected to the electrodes (105, 110, 115) which supplies a voltage wave-form to each group of electrodes, where each voltage wave-form for each group is phase-shifted relative to the other phase-shifted wave-forms.
