摘　　要：概括了目前CO气体传感器的国内外发展状况,提出了传统电化学气体传感器存在的问题,介绍了一种利用Nafion膜为固态电解质的CO气体传感器,阐述了它的工作原理。对电极材料?薄膜材料?固态电解液?电路等关键技术进行了讨论,重点介绍了电极的活化、液态电解质的固化及传感器的抗干扰、抗恶劣环境影响等技术研究,给出了传感器的结构和电路原理图,讨论了传感器的性能特点和发展方向。Development conditions of CO（carbon monoxide） gas sensors of internal and external were generalized. The problem of traditional electrochemistry gas sensor was proposed. A new type of CO gas sensor used Nafion membrane as whole solid electrolyte was introduced, and its work principle was described. Key technology, such as material of electrode, membrane, solid e- lectrolyte, circuit, were discussed. Study of activation of electrode, solidify of liquid electrolyte, resist disturb and scurviness environment capability of sensor were introduced. The structure and circuit principle of gas sensor were explained and its characteristics, features and development direction were discussed.
