Abstract: A wireless circuit including an electrode array with a nanoscale dielectric disposed between two electrodes allows for wirelessly powered manipulation of particles in a liquid solution, air, or gaseous media via dielectrophoretic forces. The electrode array includes a first electrode, a second electrode, and a nanoscale dielectric layer between the first and second electrode. An inductive coupler is operatively coupled to the electrode array and configured to receive wireless power or wireless signals.

Abstract: A microfluidic device includes a bottom electrode, a dielectric layer on the bottom electrode, one or more top electrodes on a region of the dielectric layer, Each of the one or more top electrodes has a sidewall that forms a sidewall angle with an outer surface of the dielectric layer that is less than 180 degrees. The sidewall of each of the one or more top electrodes and a portion of the outer surface of the dielectric layer adjacent to the sidewall define a microchannel region for transporting an open microchannel of a fluid. Such microfluidic devices may enable transport of small microchannels using low voltages.
