How to solve the problem of individual existence in the existing gas sensor array response characteristics drift inconsistent, and make it lower operating temperature and better sensitivity, has been committed to the goal for researchers. Single-walled carbon nanotubes have attracted much attention for its semiconductor properties. Combine it with the metal oxide film as the sensitive odor detection chip unit, not only improve the sensitivity, but also reduce the operating temperature effectively. The topic purpose of studying is making one microstructure odour detection chip based on single- walled nanometer nanotubes and the metal oxide compound thin film in a body. We will develop the research on the high sensitive nanometer structure thoroughly, study the processing craft such as the electric arc processing and sputtering technology deeply, discuss the effect of the sensitivity caused by the thin film structure,the integration technology,the encapsulation technology and the testing technology,etc .The research will lay the foundation to realize the miniaturization and the integration of odour sensors and the batch production. This topic involved research in our industry and agriculture, civil, disaster prevention, environmental protection, medical care, security, and many other areas have great application prospect.
