电子鼻——智能气体传感器

Electronic Nose──Intelligent Gas Sensor

论述了应用模式识别技术和气体传感器阵列所研制的模拟嗅觉系统.气体传感器阵列由8个金属氧化物气敏器件组成,它们对不同的气味和气体有不同的响应;传感器阵列输出的信号经过微机处理和识别.作者对实验过程进行了详细的讨论,实验结果表明该系统可成功地识别多种不同的气体.

This paper describes an analogue odor-sensing system using the patternrecognition technique together with a gas sensor array. The gas sensor array consists ofeight metal oxide sensors which have different sensitivities to various odors and gases.The output signals of the sensor array are processed and identified by a personal com-puter. Experimental procedures are discussed in detail and the results show this systemcan successfully discriminate various gases.
