OE-MEMS Chip-Based Mass Sensor for Chemical, Gas, and Bio-Hazard Sensing (ISR IP)

All three techniques have inherent disadvantages. The first requires an electric signal that is subject to electromagnetic interference (EMI), the second has all the disadvantages of intensity measurement technology, including lack of portability and sensitivity to optical power fluctuations, and the third technique requires uneven application of piezoelectric material to the two faces of the cantilever.
Inventors at the University of Maryland have developed a reliable and low-cost detection system having immunity to EMI, from a wavelength shift of a light source, a wide dynamic range and a high accuracy unaffected by a noisy environment that has turbulent gas flow, abrupt pressure changes or mechanical vibrations.
In addition, the invention employs an integrated VLSI processing module allowing for a smart sensor configuration.
