Abstract

We fabricated the gas sensor using carbon nanotubes (CNTs) and investigated the detection properties for NH3 gas. The sensing material of gas sensor is employed multi-wall carbon nanotubes (MWNTs). The CNT gas sensor structure is realized with technologies of micro-electro mechanical systems (MEMS). The nanotubes gas sensor is operated at room temperature. And the electrical resistance of the carbon nanotubes is measured upon exposure to NH3 gases. Also, recovery time of CNT gas sensor is measured according to temperature.
