Abstract:
A current control device comprising:(a) two electrodes electrically conductive and non-movable; (b) an isolator electrically nonconductive and non-movable; (c) at least one pressure plate electrically nonconductive and movable; (d) at least one dynamically controllable actuator comprising an active element lengthwise disposed and capable of lengthwise dimensional variations when activated by an electrical charge separate and distinct from a current passing through said electrodes, said dynamically controllable actuator fixed at one end and attached at a second end to said pressure plate; and (e) a pressure conduction composite, said pressure conduction composite and said isolator disposed between said electrodes, said pressure conduction composite contacting without separation said electrodes, said isolator, and said at least one pressure plate, said pressure conduction composite either resistive or conductive based on presence or absence of compression imposed by said at least one pressure plate.
