Abstract
Official abstract text for this publication.
The present invention, in one embodiment, provides a method of measuring pressure or temperature using a sensor including a sensor element composed of a plurality of carbon nanotubes. In one example, the resistance of the plurality of carbon nanotubes is measured in response to the application of temperature or pressure. The changes in resistance are then recorded and correlated to temperature or pressure. In one embodiment, the present invention provides for independent measurement of pressure or temperature using the sensors disclosed herein.
First claim
Opening claim text (preview).
What is claimed: 1. A method of measuring temperature comprising: providing a sensor element composed of a plurality of electrically interconnected nanostructures having a fixed number of junctions between each of the electrically interconnected nanostructures in a temperature range of 0° K to 550° K; applying a current through the electrically interconnected nanostructures, measuring electrical properties of the electrically interconnected nanostructures in response to an application of temperature to the sensor element comprised of the plurality of electrically interconnected nanostructures, the measuring of temperature is independent of pressure, and correlating the electrical properties of the electrically interconnected nanostructures to temperature. 2. The method of claim 1 , wherein the plurality of interconnected nanostructures are fixed to a rigid substrate, the rigid substrate has a shear modulus of 0.1 Gpa or greater. 3. The method of claim 2 , wherein the electrically interconnected nanostructures are carbon nanotubes having a purity of greater than 50%. 4. The method of claim 2 , wherein the electrically interconnected nanostructures are carbon nanotubes having a purity of greater than 90%. 5. The method of claim 2 , wherein the plurality of electrically interconnected nanostructures is disposed in a single layer on the rigid substrate.
