Invited webinar on "Design and Development Methodology of a Chemiresistive Gas Sensors: Past, Present and Future"

#gas #sensors #MEMS

Mr. Rahul has discussed the history of gas sensors, the current trends in gas sensors,s and future scope in the same field. Beginning of his talk, he has explained the correlation of five human senses with the sensor field. After that, he has explained the journey of the sensor field where it started from and how far it has reached. He has talked about the characteristics of gas sensors. In his talk, he has described four types of gas sensors such as resistive, capacitive, acoustic, and optical gas sensors. In addition to that, he has also explained in detail various resistive type gas sensors. He has also covered the fabrication process of the microelectronic mechanical system-based sensor in depth. He has also shared realistic examples of MEMS-based devices we are using in our daily life.  In his talk, he has also explained the microheater simulation for MEMS-based devices. His research talk mainly focused on the metal oxide-based resistive sensor which also consists importance of grain boundaries in sensing.
