The concept of sensors and processing is undergoing many changes due to major strides in electronics and communications. The current notion of measurement follows the idea of “measure everything”, “measure all times,” “measure from anywhere” has challenged the researchers to re-examine how sensing is done, sensed data is managed and information is extracted. Currently, research is focussed on developing sensors that are (a) cheaper so that they can be easily deployed everywhere, (b) physically “small” and unobstrusive, (c) wireless and able to communicate “on demand” and “at will”, (d) low powered (“green”), (e) able to preprocess the data before communicating, (f) able to self identify, self validate, self calibrate and, be fault tolerant. Smart sensing and Sensing smartly becomes crucial in this connected world. “Intelligence” at sensing, communicating and processing levels are desired in all applications. With all these advancement, one has to make a hard choice between quality of data and quantity of data. Quality is dependent on the type of sensing (contact or non-contact) while quantity may be attributed to ubiquitous nature of sensing. Quantity and quality of sensed data affect the extraction and interpretation of information. Furthermore, when processing is outsourced, issues of privacy and security become an issue. In all, is sensing in the connected world: A curse or a boon?


Prof. Sreeraman Rajan is a Canada Research Chair in Sensor Systems in the Department of Systems and Computer Engineering in Carleton University, Ottawa, Canada since 2015. Since 2020, he is the Director, Ottawa Carleton Institute for Biomedical Engineering. Before joining Carleton University, he was with Defence Research and Development Canada (DRDC) Ottawa, Canada as a Senior Defence Scientist. He has worked in the areas of nuclear science and engineering, control, electronic warfare, communication and biomedical engineering while in industry. He is currently the Chair of the IEEE Ottawa EMBS and AESS Chapters. He has served IEEE Canada as its board member (2010-Oct 2018) and the IEEE MGA in its Admissions and Advancement Committee, Strategic and Environment Assessment Committee. He was awarded the IEEE MGA Achievement Award in 2012 and recognized for his IEEE contributions with Queen Elizabeth II Diamond Jubilee Medal in 2012. IEEE Canada recognized his outstanding service through 2016 W.S. Read Outstanding Service Award. IEEE Ottawa Section recognized him as an Outstanding Volunteer in 2012 and an Outstanding Engineer in 2018 and an outstanding researcher in 2019. Carleton has recognized him as an outstanding graduate mentor and students have recognized his teaching through CUASA Teaching Award. The Faculty of Engineering and Design recognized his research and awarded him in 2019. He has been involved in organizing several successful IEEE conferences and has been a reviewer for several IEEE journals and conferences. He is the holder of two patents and two disclosures of invention. He has authored more than 170 journal articles and conference papers. He is a Senior Member of IEEE, a member of IEEE Instrumentation and Measurement, Engineering in Medicine and Biology, Signal Processing and Aerospace and Electronic Systems Societies. He is the chair for Ottawa chapters of IEEE Engineering in Medicine and Biology Society and Aerospace and Electronic Systems Society.
