Wireless Vital Monitoring for Sleep

The significance of sleep quality has drawn substantial attention, given its direct impact on daily functioning and long-term well-being. Two key vitals for sleep monitoring are breathing and heartbeats. In this paper, we present an approach to wireless monitoring sleep using Frequency-Modulated Continuous Wave (FMCW) radar technology. We explore the utilization of both Infineon Position2Go (24GHz) and Texas Instruments IWR 6843 (60GHz) sensors to detect and analyze vital signs - breathing and heart rates. Our method em- ploys different signal processing techniques like Range FFT, phase unwrapping, and selective bandpass filtering. We address some key challenges in high-frequency radar signals and demonstrate how optimized configurations enhance the reliability of vital signs detection. The findings reveal significant insights for sleep health monitoring, paving the way for non-contact, real-time health track- ing, and comprehensive sleep analysis.
