Carbon nanotube film sensor

摘要：

Carbon nanotubes change their electronic properties when subjected to strains.In this paper,the strain sensing characteristic of the carbon nanotubes is used to develop a carbon nanotube film sensor that can be used for strain sensing at macro scale.The carbon nanotube film is isotropic due to randomly oriented bundles of Single Wall Carbon Nanotubes(SWCNTs).Using experimental results it is shown that there is a nearly linear change in voltage across the film when subjected to tensile and compressive stresses.The change in voltage is measured by a movable four point probe in contact with the film.Multidirectional and multiple location strains can be measured by the isotropic carbon nanotube film.
