气体传感器技术及发展现状

摘要

气体传感器已广泛用于电子舌、电子鼻等仿生系统的设计.在环保检测、食品工业、毒品检测、反恐防恐、以及人类疾病的早期预测和实时在线监控等方面具有重要的应用价值.本文概述了气体传感器的研究进展和发展现状.%Gas sensitive materials and gas sensors have been widely used in the design of lectronic nose and electronic tongue of bionic systems. Tliey have many potential applications in food industry, environmental monitoring, anti -terrorism, the inspection of drugs and toxic gases, and the prognoses of some diseases. It is important to study the sensors consisted of organic films with high sensitivity, rapid response and good reproducibility and research the relationship among the materials, technologies and properties of devices.
