  • Composite material switches
    Patent number: 6445280
    Abstract: A device to protect electronic circuitry from high voltage transients is constructed from a relatively thin piece of conductive composite sandwiched between two conductors so that conduction is through the thickness of the composite piece. The device is based on the discovery that conduction through conductive composite materials in this configuration switches to a high resistance mode when exposed to voltages above a threshold voltage.
    Type: Grant
    Filed: December 28, 2000
    Date of Patent: September 3, 2002
    Assignee: The United States of America as represented by the Adminstrator of the National Aeronautics and Space Administration
