  • Arrangement for producing fluid flows and/or particle flows, and a method for the manufacture and operation thereof
    Patent number: 8444837
    Abstract: A device for producing at least one of fluid flows and particles flows includes a substrate having a substrate surface. The substrate surface includes a matrix including a plurality of regions having at least one of a different magnitude of a surface charge, a different sign of the surface charge, and a different height above the substrate. A fluid including at least partially electrically charged particles is disposed at the substrate surface. A first control element is configured to supply a plurality of electrical voltages to a plurality of electrode pairs. The electric field exerts a first force on a component of the fluid within an electrical double layer. The component is disposed adjacent to the substrate surface. The electric field exerts a second force within the double layer and outside the double layer, the second force is exerted on the at least partially electrically charged particles.
