基于电子鼻的气敏传感器及其阵列

电子鼻是模拟动物的嗅觉系统设计研制的一种智能电子仪器，是利用气敏传感器阵列的响应图谱来识别气味的电子系统。本文从应用的角度出发，对电子鼻系统中常用气敏传感器的工作原理、适用范围和优、缺点进行了比较，指出了电子鼻系统中选择气敏传感器及其阵列的一些注意事项，为电子鼻特别是便携式电子鼻的研制提供参考。

Gas Sensors and Array based on Electronic Nose

Electronic nose is a kind of intelligent electronic instrument simulating animal＇s osmesthesia, which use response illustrative plates of gas sensors to recognize gas. From the pointof view of application, the working principles, application ranges, the virtues and defects of some kinds of gas sensors used frequently in electronic noses are introduced and compared with each other. Some matters being paid more attentions on in selecting gas sensors of electronic nose are pointed for giving a reference for developing electronic noses, especially portable electronic noses.
