Abstract
A device is provided that includes a stator including a stator element and a row of stator comb fingers, wherein the stator comb fingers extend away from the stator element in a y-direction. A device may include a rotor including a rotor element and a row of rotor comb fingers, wherein the rotor comb fingers extend away from the rotor element in a direction which is opposite to the y-direction, and wherein the stator comb fingers are interdigitated with the rotor comb fingers, and form an interdigitated row, and each pair of adjacent stator comb finger and rotor comb finger are separated from each other by a x-gap in a x-direction, which is perpendicular to the y-direction.
