    Abstract: A sensor has a plurality of carbon nanotube (CNT)-based conductors operatively positioned on a substrate. The conductors are arranged side-by-side, such as in a substantially parallel relationship to one another. At least one pair of spaced-apart electrodes is coupled to opposing ends of the conductors. A portion of each of the conductors spanning between each pair of electrodes comprises a plurality of carbon nanotubes arranged end-to-end and substantially aligned along an axis. Because a direct correlation exists between resistance of a carbon nanotube and carbon nanotube strain, changes experienced by the portion of the structure to which the sensor is coupled induce a change in electrical properties of the conductors.

    Abstract: A sensing system for quantifying a gaseous species or an analyte in a sample in accordance with one embodiment of the present invention includes a light emitting diode and a detector. The light emitting diode is coupled to a power source and at least a portion of the light emitting diode is coated with a sol-gel-derived film doped with a doping material. The detector is spaced from and substantially across from the portion of the light emitting diode coated with the sol-gel-derived film. The system may include a filter which is located between the light emitting diode and the detector and a processing system which is coupled to the detector for quantifying the amount of a gaseous species or an analyte in a sample based on data from the detector.

    Abstract: A sensor having a substrate overlayed with a sol-gel layer, a chemical sensing species deposited upon the sol-gel layer, and a thin film of a second sol-gel layer overlaying and entrapping the species. The effect of this sensor is that the species exhibits a significant portion of its intrinsic function over a period of time. In yet another embodiment of the subject invention, a method is disclosed to form a thin sol-gel layer upon an ambient substrat. This method ensures the integrity, stability and functionality of the chemical sensing species within the sol-gel layers.
