  • Combustible gas diode sensor
    Patent number: 6474139
    Abstract: A combustible gas sensor diode including a SiC semiconductor substrate, on top of which an AlN layer and a catalytic metal “gate” electrode are deposited is disclosed. The combustible gas sensor diode can be operated in either a D.C. forward conduction mode or an A.C. reverse bias mode. Methods of detecting combustibles in both D.C. and A.C. modes are further disclosed.
    Type: Grant
    Filed: February 6, 2002
    Date of Patent: November 5, 2002
    Assignee: Ford Global Technologies, Inc.

  • Combined combustible gas sensor and temperature detector
    Patent number: 6418784
    Abstract: A substrate covered with an insulating layer and a catalytic gate electrode 26 disposed on the insulating layer. The catalytic gate electrode 26 has a first end having a first contact pad 30 and a second end having a second contact pad 32. A meander 28 is placed between the first contact and the second contact. A third contact pad 24 is coupled to the underside of the substrate 22. The temperature is measured between the first contact pad 30 and second contact pad 32 while sensor's response to gas concentration is sensed between the gate electrode 26 and the third contact 24.
