A novel gas ionization sensor based on corona discharge using carbon nanotubes (CNTs) was proposed. The sensor utilized unique physical structure and the field emission effect of CNTs. Due to adopting the method of anodic aluminum oxide (AAO) template to grow aligned CNTs, the electrode and CNTs were integrated, so the gas sensor simplified its structure and processing technics. As controlled DC voltage was applied to the CNTs electrode, the sharp tips of CNTs generated high electric fields, so it was easy to produce corona discharge at low voltages. As different gases have their unique breakdown voltage and discharge current, it is possible to identify one gas or certain mixture gases. In order to improve the sensitivity of the sensor, the device of generating stochastic resonance was used in the measuring circuit firstly, and the range of detecting concentration was increased greatly. The influences of temperature and humidity were discussed, and the performance of the sensor was also evaluated. Experimental results show that the CNTs gas sensor has the merits of small size, fast response, good sensitivity and selectivity. It is very convenient to be operated at room temperature and feasible in gas detection.
