  • Sensors and switches for detecting hydrogen
    Patent number: 8383412
    Abstract: Sensors and switches for detecting hydrogen include an electrically-insulating support; a first and second electrode; and a palladium structure alone or in combination with an organic insulating film. The palladium structures of the sensors are deposited on and contact a first electrode and a portion of the palladium structure extends to and contacts the second electrode to create a conductive path. The palladium structures of the switches are deposited on and contact a first electrode and a portion of the palladium structures extend to and contact an organic insulating film deposited on the second electrode. Upon exposure of the switch to hydrogen, portions of the palladium structure extend through the film and contact the second electrode to create a conductive path. Methods of detecting hydrogen and methods of fabricating a sensor for detecting an analyte of interest are also provided.
    Type: Grant
