  • Chemical switch for detection of chemical components
    Patent number: 5939020
    Abstract: A chemical switch device comprising a film which irreversibly reacts upon exposure to specific chemical components in the environment under the conditions of measurement. The reactions can lead to large changes in the physical and chemical properties of the film which are measurable electrically, optically or by other methods.
    Type: Grant
    Filed: June 1, 1995
    Date of Patent: August 17, 1999
    Assignee: The Arizona Board of Regents, A Body Corporate of the State of Arizona, Acting for and On Behalf of Arizona State University
