Robust Non-contact RF Sensing for Human Vital Sign and Activity Monitoring
Non-contact sensing for vital signs and human activities utilizing wireless signals has attracted a lot of attention in the last few years. Sensing using Ultra-wide-band or milli-meter wave radios is advantageous in its ability to penetrate garments or walls, operate under different lighting and weather conditions, and better preserve people’s privacy. Despite successful research demonstrations, there remain significant gaps in practical adoption and deployment. Many challenges need to be addressed to handle the presence of multiple subjects, subject diversity and environmental interferences. In this research program, we aim to develop robust non-contact sensing solutions to detecting vital signs and extracting high-level analytics of human activities in indoor and in-vehicle environments. The projects are expected to not only advance the state-of-the-art in algorithmic design for non-contact RF sensing but also develop proof-of-concept prototypes and demonstrative applications.
