The currently popular electrochemical gas sensors are mostly steady with regard to their operating state. As a result, the further improvement of sensor characteristics is restricted by such a “steady state”. Based on the transient electrochemistry principle, a kind of all\|new transient electrochemical multi\|component gas sensors—— “potential pulse modulated gas sensors”, which combines computer\|controlled fast modulated potential technique with microelectrode, has been established. This novel approach provided a real\|time and dynamic transduction technique integrated with detection, treatment and display of signals. As compared with conventional steady electrochemical gas sensors, the transient electrochemical multi\|component gas sensors have made a new breakthrough in optimizing the sensor performance and developing the sensor functions, as illustrated by the case of detection of respiratory gases CO 2 and O 2. 暂态电化学传感器 电势脉冲调制型气体传感器 微电极 多组份气体 10.14188/j.1671-8836.2000.02.010 TP212 国家自然科学基金资助的课题!（ 3 9970 2 11） 2000-02-01 2021-04-01 2
