Claims
- 1. A reversible resistant device comprising:
- a first conductive layer,
- a second conductive layer opposed relative to said first conductive layer,
- a normally non-conductive film disposed intermediate said first and second conductive layers,
- said normally non-conductive film comprising metal particles having a non-conductive coating thereover disposed within a first binder, and
- a conductive film located intermediate said normally non-conductive film and said second layer, said conductive film comprising metal particles dispersed within a second binder,
- said metal particles protruding from said first binder up to 25% of their diameter,
- whereby upon being exposed to an electrical force said non-conductive coating breaks down to render said normally non-conductive film conductive.
- 2. The device of claim 1 wherein said metal particles of said normally non-conductive layer are aluminum and said coating thereover is aluminum oxide.
- 3. The device of claim 2 wherein said second binder is a polymer dispersed in a weak binder.
- 4. A method of producing a reversible resistant device, the steps comprising:
- producing a normally non-conductive film by dispersing within a first binder metal particles having thereover a non-conductive coating which has the property of breaking down when exposed to an electric force with up to 25% of the diameter of the metal particles protruding from the first binder,
- applying the normally non-conductive film to a first conductive layer,
- applying a conductive film comprising metal particles dispersed within a second binder to the normally non-conductive film and,
- placing a second conductive layer over said normally non-conductive film.
- 5. The method of claim 4 wherein said conductive film is formulated by dispersing conductive flakes in a dispersion of a polymer in a weak solvent.
