Dr. Ramesh K Sonkar received the B. Tech. degree in Electronics and Communication Engineering, M.Tech. and Ph.D. degrees in Electrical Engineering from Indian Institute of Technology (IIT) Roorkee, IIT Kanpur and IIT Kanpur, India, in 2001, 2003 and 2012 respectively. He has been with the Department of Electronics and Electrical Engineering at the Indian Institute of Technology Guwahati since 2011 as Assistant Professor. His research interests include Optoelectronics Device Characterization and Fabrication, Photonics Integrated Circuits, Integrated Optics, Fiber Optics Communication, Non-invasive Measurement of Physiological Parameters of Human Blood, fiber lasers, Structural Health Monitoring, and Antennas. He is recipient of Young Faculty Research Fellow of Visvesvaraya PhD Scheme, Ministry of Electronics and Information Technology, Government of India. He has authored more than 20 journal and conference papers. Currently 4 Ph.D. students are doing their research under his supervision. He has completed 1 projects as a Co-PI worth of about Rs. 50 Lakh and there are 2 on-going projects worth of Rs.3 crores.
Non-Invasive Measurement of Vital Physiological Parameters of Human Blood Using Photonics: The past decade has seen a significant rise in the use of non-invasive diagnostic methods such as X-rays, Ultrasound, Lithotripsy, Magnetic Resonance Imaging (MRI), Thermography and many more. Non-invasive methods are those which don’t involve a break in skin or one where there is no contact with the mucous membrane. Currently, blood component measurements are done using invasive methods which involve blood to be drawn from the patient and then its analysis. Apart from the pain, infection and scars caused due to incisions, there is another major drawback which is these methods do not allow portable real time patient monitoring during critical situations as well as create huge bio waste. The non-invasive device presented has no risk of bleeding, is completely portable and can be used for real time monitoring which allows immediate treatment of patients.
