PERFORMANCES OF A NEW GENERATION OF METAL OXIDE GAS SENSOR BASED ON NANOSTRUCTURED-SnO 2 AND ON HIGH OPERATING TEMPERATURE MICROHOTPLATE

Abstract : The sensor presented in this article consists of a nanostructured SnO2 as high sensitive material and an efficient high temperature microhotplate. Tin oxide nanoparticles are in suspension in a solvent (colloidal solution) and then are deposited by contactless methods such as microinjection that insure a good control of thin films deposition. A new efficient microhotplate has been developed with high electrical and mechanical stabilities up to 600°C with a low power consumption (<70mW) and allows an efficient control of temperature, useful for detection of gases. In this work, our new generation of metal oxide gas sensor is exposed to different polluting gases like CO, C3H8 and NO2 at different temperatures to determine the optimum operating temperatures which allow obtaining the highest sensitivity for each gas and then a good selectivity. We also demonstrated that these gas sensors present a better sensitivity and above all a better stability compare to commercial metal oxide gas sensors
