Gas Sensor's Group

Gas sensors are extremely useful in a variety of applications, such as environment monitoring, industrial manufacturing units, defense, human health, Space research, and safety.
Air pollution is one of the most emerging problems in our surroundings. Strict regulation of the emission of toxic gases requires fast and highly selective gas sensors capable of detecting the sub-ppm level of gases. Human expired breath contains a plethora of volatile organic compounds; volatile sulphur compounds and also mixture of nitrogen, oxygen and carbon dioxide in ppt to ppm concentration range. So, the analysis of breath can potentially provide important diagnostic information, which can be used as biomarkers in the evaluation of health status and disease types.
The constant need for gas sensors with high sensitivity, fast response/recovery, low operating temperatures, and good stability continues to stimulate the progress in gas sensing technologies, especially of miniaturized device forms intergated with novel sensing materials. Therefore, to achieve these desired performance metrics of gas sensors to use them in various applications, it is very important to make efforts on rational device design and investigate novel sensing material (s) for next generation gas sensor devices....
