Human physiology and contactless vital signs monitoring using camera and wireless signals

Abstract Vital signs monitoring has become increasingly more important because it can offer useful clues to medical conditions such as cardiovascular disease, sleep disorders, or anomalies. There is a compelling need for technologies that enable contactless, easy deployment, and long-term vital signs monitoring for healthcare. In this chapter, we discuss human physiology and contactless physiological monitoring using remote cameras, radio-frequency (RF) based sensing techniques (e.g., radar, received signal strength (RSS), channel state information (CSI), and RFID), and acoustic-based sensing techniques.
