Navakanta Bhat received his Ph.D. in Electrical Engineering from Stanford University, Stanford, CA in 1996. Then he worked at Motorola’s Networking and Computing Systems Group under Advanced Products R&D Lab (APRDL) in Austin, TX until 1999.
He joined the Indian Institute of Science, Bangalore in 1999 where he is currently a Professor and Chair, Centre for Nano Science and Engineering. His current research is focused on Nanoelectronics device technology, Biosensors for point of care diagnostics and Gas sensors for pollution monitoring. He has 240 research publications in international journals and conferences and 10 granted US patents and 14 pending patents to his credit. He was instrumental in creating the National Nanofabrication Centre (NNfC) at IISc, Bangalore and served as the chairman of NNfC administration committee from 2010 to 2015.
He is a Fellow of the Indian National Academy of Engineering. His research accomplishments have been recognized through several awards including the prestigious Dr. Abdul Kalam Technology Innovation National Fellowship (2018) and Prof. Rustum Choksi award for Excellence in Engineering Research (2017).
He is a member of the Board of Governors of the IEEE Electron Devices Society and also the Chair of Nanotechnology technical committee and is the chief-editor of the IEEE TED special issue on “2D Materials for Electronic, Optoelectronic and Sensors”. He is the founder and promoter of a startup company, PathShodh Healthcare Pvt Ltd (www.pathshodh.com) which has developed the first of its kind multi-analyte point-of-care diagnostic device for 5 blood tests and 3 urine tests, related to multiple chronic diseases including diabetes and its complications, anemia and malnutrition, kidney and liver diseases. PathShodh has received numerous recognitions and it’s product has already been used for rural health screening including the partnership with Tata Trust in deploying PathShodh technology for rural Telemedicine project serving several villages.
In this talk, I will start with a brief description of various research initiatives at the Centre for Nano Science and Engineering in the Indian Institute of Science Bangalore. Then I will focus on two major threads pursued in my research group. Nanostructured metal oxide gas sensors help in pushing the boundaries of sensitivity and limit of detection. I will present various device architecture and process technologies, such as suspended core-shell, metal semiconductor GasFET exploiting work function modulation, harnessing electromigration and plasma oxidation to create core-shell structures, polystyrene beads to achieve lithography free hexagonal nanostructures for high performance gas sensing. I will also present the results on single-chip gas sensor array for environmental pollution monitoring to quantify, CO, CO2, NO2, and SO2. In the contact of biosensors, I will present our work on physiology inspired electrochemical biosensors exploiting novel chemical receptors. I will conclude by illustrating our translational work in biosensors, in commercializing lab-on-palm device for the measurement of 5 blood markers and 3 urine markers for the management and early diagnosis of multiple chronic diseases such as diabetes, kidney and liver disease, anemia and malnutrition.
