Sensor devices of gas produced with carbon nanotube films automontados

摘要

Sensor devices of gas produced with automontados films of carbon nanotubes. Carbon nanotubes exhibit variations in their electrical resistance when they come into contact with some types of gases, enabling the identification of the presence of these. However, the intensity of the variation is difficult to detect.Techniques for the formation and deposition of nanostructured films can provide significant improvements in physical properties of the films to improve the siua applicability.The construction of a gas sensing device based on nanostructured films of carbon nanotubes carbobo, deposited by the method of film forming automontados in net interfaces, was able to detect the presence of gases extremely efficiently through the monitorame Nt of the electric resistance of the device.
