Electromagnetic-wave modulating, movable electrode, capacitor elements

摘要

Inventive electromagnetic-wave-modulating capacitors with movable electrodes are low-cost, low-energy, reliable and fast-acting elements for employment in highly transparent, conductive fixed electrodes and are incorporated, among others, in reflective display pixels for large and small-scale video displays, including full-color displays where multiple such capacitors are aligned in a single pixel. Further embodiments, not necessarily with a transparent electrode, are assemblable into array antennas deployable in outer space; provide digitally controllable or responsive such variable capacitors; and in mechanically active applications can be constituted as accelerometers, or in microrobotics. Constructions with ultra-thin electrodes have special advantages.
