Electrophoretic deposition of CuO particulate thick film for ethanol sensing Anisha Bandyopadhyay, Kamalika Mandal, Vibhav Ambardekar, Debasish Das, S. B. Majumder Journal of Materials Science Materials in Electronics, 2021 Detection of volatile organic compounds is of utmost importance in numerous applications such as medical diagnosis, air quality monitoring, hazardous gas detection and food industry. In the present work, investigation on the ethanol-sensing performance of CuO thick film fabricated by electrophoretic deposition (EPD) technique was done. Oval-shaped CuO powder is prepared at room temperature via a facile wet chemical method. A simple, versatile and reproducible electrophoretic deposition technique is employed to fabricate thick film of the as-synthesized CuO powder on to a non-conducting alumina pellet. The sensing performance of EPD-grown thick film CuO sensor has been investigated in static ambient. The uniform and porous sensing layer fabricated by EPD technique exhibits good sensing characteristics such as high response % (~ 129%), quick response (38 s), recovery (462 s) time and stable baseline resistance. For better understanding of sensing performance, theoretical analysis such as stability of the sensing element analysis and response versus temperature simulation were performed. Characteristics constant response time (~ 88 s) is obtained for different test gas concentrations in the range of 50 ppm to 300 ppm. From response versus temperature simulation, activation energies of transduction and first-order kinetics were estimated as 29.43 kJ/mol and 62.99 kJ/mol, respectively.
Sensing Capability of Air Plasma-Sprayed SnO2 Coating in the Presence of Hydrogen and Carbon Monoxide V. Ambardekar, P. P. Bandyopadhyay, S. B. Majumder Journal of Materials Engineering and Performance, 2019 This report deals with the sensing characteristics of hydrogen (H2) and carbon monoxide (CO) gases using a tin oxide (SnO2) functional coating deposited on an alumina plate using air plasma spraying technique. This coating exhibits a porous morphology that contains both mesoporous and macroporous regions conducive to superior gas sensing. Initially, gas sensing measurements were performed by varying the operating temperature at a fixed gas concentration using a dynamic sensing setup. The coating showed maximum response % at 275 °C for H2 and CO gases. However, higher response % was obtained in the presence of H2 over CO. Sensing performance was further investigated by varying the target gas concentration at 275 °C. The coating exhibited a higher response for H2 compared to that of other plasma-sprayed SnO2 coating reported in the literature. The SnO2 coating under investigation demonstrated good sensor response and repeatability, moderate operating temperature and quick response time.
