Electro-chemical gas sensor for multi-gas detection application


In the recent past, there is a tremendous need for automotive exhaust emission monitoring and air quality monitoring (Indoor). The existing gas sensors can detect only single gas at a time and sensor arrays are being used for multi-gas detection application which has many drawbacks like poor accuracy, bulky circuit, non-reliable, costlier and etc. To overcome the drawbacks of the existing sensor arrays, there is a need to develop a novel gas sensor using advanced developments in the sensor fabrication and with new electrode and electrolyte materials. So there is a tremendous need for developing a gas chromatography instrument with a single sensor element in order to have cost effectiveness, compact, linear, good accuracy and reliable.
Keywords: Solid electrolyte (YSZ), multi-metallic electrodes, multi-gas detection, Cyclic Voltammetry, Voltammogram
