Abstract:
1. 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 actuator wherein said actuator is a piezoelectric element, a piezoceramic element, an electrostrictive element, a magnetostrictive element or a piezo-controlled pneumatic element, each said actuator fixed at one end and attached at a second end to one said pressure plate; and (e) a pressure conduction composite, said pressure conduction composite and said isolator disposed between said electrodes, said pressure conduction composite confined by and contacting without separation said electrodes, said isolator, and said at least one pressure plate, said pressure conduction composite either resistive or conductive dependent on a force applied to said pressure conduction composite by each said pressure plate.
