  • Reversible resistant device
    Patent number: 4940959
    Abstract: A reversible resistant device having the property of being normally non-conductive, but being adapted to being converted to the conductive state. This change in conductive state is achieved by subjecting the device to a high voltage or high electric field. The essence of the device is a normally non-conductive film located between conductive layers, the film being formed by metal oxide coated metal particles embedded in a binder. When subjected to a high a potential, the metal oxide coating loses its dielectric properties and renders the film conductive.
