Sensor Devices & Metrology

The group focuses on the development of smart sensors for the detection of atmospheric pollutant gases like COx, NOx, SOx, H2S, NH3 etc. and electromagnetic radiations based on thin film/nanostructures of metal oxides, III-nitrides, 2D materials, etc. The group is equipped with various thin film growth systems and thin film and sensor characterization facilities. Prototype metal-oxide based sensing device for CO gas has been designed and fabricated on alumina substrate with integrated platinum hot plate. Highly responsive UV photo-sensors have been developed based on III-nitride epitaxial layers and nanostructures.

Development of sensor devices for the detection of hazardous gases and electromagnetic radiations.

Testing, validation and certification of the commercially available portable gas sensor devices are required in order to ensure reliable measurements. CSIR-NPL being the national measurement institute (NMI), we are in the process of creating a National facility for testing and certification of solid-state gas sensors following ISO 17025:2017.
