Video Title
Metal Oxide Sensors Basics and Sample Implementation of a Measurement System
Abstract
In this vide the basic of metal oxide gas (MOX) sensing structure and working principles a are provided. In recent years, many studies have been carried out with the aim of understanding the surface reactions of MOX sensors, with special attention to simple cases, i.e. interaction with mixtures of oxygen (O2), carbon monoxide (CO) and water vapour. Many papers have discussed this subject, and some simplified models were developed and applied by different researchers . In this video a sample structure of a gas sensor is presented as well as a sampling system and a measurement architecture.
Brief Bio
Marco
Mugnaini
graduated in Electronics Engineering in 1999 and got his Ph.D. from the University of Florence in Reliability Availability and Logistics (Mechanics) in 2003. Since then He worked with General Electric as product safety engineer in the
Oil&Gas
business until 2005. He was appointed as Faculty at the Higher Colleges of Technology ADMC from 2012 to 2013. Presently he is with the Information Engineering Dept. of the University of Siena as Assistant Professor. His main activities concern the reliability availability and safety design of complex electro-mechanical systems with applications to sensor diagnostic and railway signalling interfaces design.
