SENSING WATER VAPOUR |
| 摘要 |
A water vapour sensor comprises a substrate and a film of carbon nanotubes impregnated with surfactant on the substrate. The substrate is of material which is inert relative to the film. Two or more electrical conductors are in contact with in spaced apart zones of the film, whereby the impedance of the film may be measured. The sensor is housed in housing which protects the sensor but also allows exposure of the film to water vapour. |

1. A water vapour sensor comprising: a substrate and a film of carbon nanotubes impregnated with surfactant on the substrate, the substrate being inert relative to the film; at least two electrical conductors in spaced apart contact with the film, whereby the resistance of the film may be measured; and a housing containing the substrate and film, the housing allowing exposure of the film to water vapour. |
