Title: Past, Present, and Future of Biomedical Radar Sensors
Abstract: The past decade has witnessed tremendous progress in biomedical radar sensors that use microwave signals to wirelessly sense various human life activities. This non-contact technology is projected to take important roles of in-patient and out-patient healthcare, assisted living, and human-machine interface. This talk first reviews the electronic developments on biomedical radar perception systems. Based on the state-of-the-art engineering technologies, recent advancements made by researchers worldwide in both engineering lab and pre-clinical/clinical environments will be discussed, including human behavior recognition, occupancy tracking, blood pressure monitoring, speech recognition, and sleep medicine. Contributions from both academic and industrial R&D groups will be included. After discussing the current challenges facing scientists and practitioners, future research directions will be laid out for ubiquitous deployment of biomedical radar sensors at the human-microwave frontier.
