This article deals with ammonia gas sensor based on carbon nanotubes. Active layer is deposited on a flexible substrate by new deposition technique called Aerosol Jet.
The deposition technique remove deficiency of today’s common used deposition technique, where it is very difficult to deposit a thin homogeneous layer of carbon nanotubes. The final sensor was tested against to 50 ppm ammonia concentration at the room temperature. The electric parameter changes of the sensor during the testing was measured by AC LRC bridge and achieved results are discussed.
