  • Analyte accumulation device
    Patent number: 7615189
    Abstract: A device for accumulation of vapor analytes incorporating nanotubes grown by CVD is described. The devices are used in sensors and as a preconcentrator for a gas chromatograph.
    Type: Grant
    Filed: June 3, 2005
    Date of Patent: November 10, 2009
    Assignees: Board of Trustees of Michigan State University, Regents of the University of Michigan
    Inventors: Dean M. Aslam, Edward T. Zellers, Yang Lu
  • Ultra-miniature optical pressure sensing system
    Patent number: 6868736
    Abstract: The fiber optic pressure sensing system includes a sensor housing formed using MEMS processing. The sensor housing has ribs and grooves in both horizontal and vertical directions relative to the surface to allow the membrane to flex in a consistent manner. The flexing of the membrane allows the pedestal to be repeatedly positioned in response to pressure acting on the extension of the sensor head and membrane.
    Type: Grant

  • Electronic device and method of use thereof
    Patent number: 6082200
    Abstract: A miniature piezoresistive sensor includes an undoped single crystal and a doped diamond film deposited by a chemical vapor deposition process on the undoped polycrystalline diamond and having a single crystal grain size of about 1 micron to 1 millimeter. The sensor preferably includes metal contacts in contact with the doped film. The resistance of the sensor varies as a function of strain on the doped diamond film transmitted through the single grain. This inexpensive highly-sensitive sensor can be used for sensing pressure, acceleration, strain or weight. It can also be used as a thermistor.
