ABSTRACT:
A system and method for measuring air quality using a micro-optical mechanical gas sensor is disclosed. According to one embodiment of the present invention, the system includes an emission source that includes a conduit gap for receiving a gas; a plurality of electrodes for applying an electric field to at least a portion of the conduit gap, the application of the electric field creating a plasma in the conduit gap; and a detector that detects an emission from the plasma. The emission source and the detector may be micro-optical mechanical devices. A method for measuring air quality is discloses. According to one embodiment, the method includes the steps of (1) placing a chip containing an emission source and a detector in a gas flow; (2) applying an electric field to at least a portion of a conduit gap within the emission source, the electric field creating a plasma; (3) detecting an emission from the plasma; and (4) processing data related to the detected emission to determine at least one constituent of the gas flow.
