Speech Title: Design, fabrication and development of metal oxide semiconductor based gas sensor system for CO₂ monitoring
Abstract: Humanity's fossil fuel (e.g. coal, petroleum) emissions in the industrial era and large-scale modification of the landscape (e.g. conversion of forests to croplands) in the past several millennia have resulted in abrupt rise in CO₂ concentration in the planet. In the recent decade, fossil fuel emissions and land cover change have contributed approximately 90% and 10% to total CO₂ emissions respectively. In addition, CO₂ absorbs infrared radiation emitted by the planet and hence has a tendency to increase the heat content and temperature of the planet. In the recent years, humanity's CO₂ emissions have averaged at about 10 billion tons of carbon per year. Out of this, 50% has stayed in the atmosphere and terrestrial plants and oceans have removed the other half. Hence, the atmospheric loading of carbon is increasing at about 5 billion tons of carbon or 2.5 ppm of CO₂ per year. With the proliferation of industries worldwide and more automobile usage, there is a growing need and interest in sensing and monitoring environmental pollutants and monitoring the concentration of chemicals/gases in industrial process control. Hence, Chemical/Gas sensing is an important requirement in environmental pollution monitoring especially for CO₂ gas. Talk focuses on the design and development of a metal-oxide based gas sensor system. Metal oxide semiconductor gas sensors represent a remarkable application of modern nanotechnologies and complex physico-chemical processes. These devices transduce a chemical quantity, such as a gas concentration, into an electric signal. Miniaturization of the device dimension coupled with the application of micro and nano fabrication processes and the use of low-cost thin film deposition technique, along with the use of a low-power sensor interface has resulted in a low-cost, low power sensor implementation.
