Abstract
A system for transporting particles includes a substrate and a plurality of spaced electrically conductive electrodes carried by the substrate. Further included is a carrier medium adapted for the retention and migration of particles disposed therein, wherein the carrier medium is in operational contact with the electrodes, and a vibration generator is positioned in relation to the substrate to impart vibrations into the carrier medium. In an alternative embodiment, the vibration generator is configured to generate an acoustic traveling wave, which includes a vibration component and a motivation component.
