A tunable-frequency system for touch-less heartbeat detection and HRV extraction
This paper presents a practical study for heartbeat detection at 1 m distance. Our microwave system, based on a vector network analyzer, is used at 2.4 GHz, 5.8 GHz, 10 GHz, 16 GHz, and 60 GHz. Heart Rate Variability is extracted from the time domain variation of the phase of S21 for both the original and the smoothed signal, and its standard deviation is calculated.
