【Abstract】 The three gas sensitive mechanisms of tin dioxide were introduced briefly. The methods such as rare metal doped, metal ions doped, metal oxides doped and multicomponent metal oxides etc. Were reviewed in order to improved sensitivity of function materials. And the electronic nose (EN) which was an instrumented chemical sensor array with pattern recognition was illuminated specially in possible application domains. At the same time, the present study tendency of tin dioxide gas sensitive sensors was envisaged.更多还原
