With the continuous increase in the number of threats to human health and safety, researchers have increasingly focused more on the topic of environmental sensors. Having a common and cost-effective platform to sense different environmental pollutants is the need of the hour. Such a platform requires mimicking the olfactory receptor neurons (ORNs) present in our biological nose, which signals the brain. In the context of ENose, they are being investigated as a block of sensing elements for various analytes. I will introduce artificial sensing devices and describe our recent experiments, where we developed electronic devices to probe and to quantify the analytes. This led us not only to observe the various signatures of analytes but also to quantify them with an analog-to-digital conversion microsystem. Such a microsystem converts the gas concentration to digital bits and provides a better understanding of the environment around us; hence, serving as the building blocks for the Enose platform.
Dr. Sandeep G. Surya received his Ph.D. degree from IIT Bombay in 2017. He is currently a Post-Doctoral Fellow with Sensors Lab, CEMSE Division, King Abdullah University of Science and Technology. Prior to this, he was a Research Associate with the Microsystems Technology Research Unit, Fondazione Bruno Kessler, Trento, Italy. His forte is in building platforms for different sensor applications and is a nominated fellow for sensors initiative program to work at Massachusetts Institute of Technology. He demonstrated experience in leading interdisciplinary research and collaborations by publishing 30 articles and two patents (authored/co-authored). Earlier, he was a member of a group working on the development of standoff explosive detection technology using OFETs and nano-electromechanical-sensors. He was also a member of the team esanjeevani, which developed a project on Telemedicine, which earned wide recognition and was adjudged first in many national level symposia. His work has received the P. P. Chhabria Award of Excellence in intelligent systems and robotics for the year 2009, the Fellowship from ISED 2011, the Gandhian Young Technological Innovation Award from IIM-A 2012. In 2019, he was awarded the “Young Achiever Award” in “International Business and Academic Excellence Awards (IBAE-2019)”, Dubai.
