CARBON DIOXIDE NANOELECTRONIC SENSOR |
摘要 |
An electronic system and method for detecting carbon dioxide is provided, using a nanostructure sensing device (CO<SUB>2 </SUB>sensor). The CO<SUB>2 </SUB>sensor is made up of a substrate and a nanostructure disposed over the substrate. The nanostructure may comprise a carbon nanotube, or a network of nanotubes. Two conductive elements are disposed over the substrate and electrically connected to the nanotube. A gate electrode may be positioned opposite the nanostructure. A functionalization material reactive with carbon dioxide is disposed on CO<SUB>2 </SUB>sensor, and in particular, on the nanotube. The CO<SUB>2 </SUB>sensor may be connected to an electrical circuit, which will respond to changes in CO<SUB>2 </SUB>concentration in the ambient sensor environment. |
