Non-Invasive Contact-less Heartbeats and Breathing Rate Monitoring (HBR-Radio)

​

The evolution of wireless communication signal processing technologies has led to the emergence of smart contact-less health monitoring approaches. In this project, a passive radar-based health monitoring system is introduced. HBR-Radio is a vital-signs monitoring system that detects heart and breathing rates without the need for anybody mounted contact-based devices. A Wi-Fi access point, using a standard 802.11 protocol, is utilized as the transmitter of the system. A Software-Defined Radio (SDR) platform is used to capture the signal transmitted directly from the source (reference signal), and the reflected signals from the surroundings including the one reflected from the monitored person (surveillance signal). To extract the desired vital signs, several signal processing techniques are utilized. The importance of the introduced system stems from the need for developing integrated smart remote ubiquitous health monitoring systems that are convenient to users in modern society. Moreover, this system enables a more dynamic and cost-efficient healthcare services for medical staff and service providers.
