(PDF) Carbon nanotubes based gas sensor | Ijariit Journal ...

CNT gas sensors made using adsorption properties are common and easy to design and contribute to large part of CNT based gas sensors. This is associated with the change in resistance of CNT due to charge transfer between CNT and gas molecules or the change in carrier lifetime due to scattering. Though this kind of sensors is common, they are in adequate for inert gases or gases with low ...

NASA - Carbon Nanotube Sensors for Gas Detection

By measuring the conductivity change of the CNT device, the concentration of the chemical species, such as gas molecules, can be measured. This sensor array with carbon nanotubes (see figure 1) has been exposed to nitrogen dioxide at various concentrations from 10ppm to 400ppb at room temperature (see figure 2) and ammonia at the concentration range of 50ppm to 5ppm at room temperature (see ...

Large-Scale Integrated Carbon Nanotube Gas Sensors

· Carbon nanotube (CNT) is a promising one-dimensional nanostructure for various nanoscale electronics. Additionally, nanostructures would provide a significant large surface area at a fixed volume, which is an advantage for high-responsive gas sensors. However, the difficulty in fabrication processes limits the CNT gas sensors for the large-scale production.

Fabrication of CNT based Gas Sensor Using Interdigitated ...

The fabricated CNT sensor was then tested with the gases like ammonia, methane. The process was repeated for several flow rates for small time duration and also fixed flow rate for a longer duration of time. Results revealed that CNT showed a good resistance change on exposure of different gas on the surface of CNTs which concludes the good selectivity of the sensor. Acknowledgements Author ...
