| 摘 要： | 医用电子鼻是一种特殊的电子鼻系统,与通用电子鼻一样,传感器系统是它的核心。现有的气体传感器主要有金属氧化物半导体型、电化学型、导电聚合物型、石英微天平等几种,但将它们用于医用电子鼻都还有不足,因为医用电子鼻对传感器系统有更高的要求,它要求气体传感器谱度更广、检测限更低、灵敏度和稳定性更好。

| Abstract: | Medical electronic nose is a sort of special electronic nose system, as general electronic nose, it is the element of sensor. Current gas sensors mainly include metal oxide semiconductor sensors, electrochemical sensors, conducting polymer sensors and quartz crystal microbalance sensors. Most of them have disadvantages as used for medical electronic nose, which has higher requirements on sensor system. Medical electronic nose needs gas sensors with broader detection spectrum,lower limit of detection as well as higher sensitivity and stability. |

| Keywords: | medical electronic nose gas sensor detection spectrum limit of detection(LOD) |
