Non-contact Determination of Heart Rate Variability Using 24 GHz Doppler Radar

Published: 20 July 2021 Publication History

Abstract

Heart Rate Variability (HRV) has become a popular medical interest as it determines the state of one's health, fitness, recovery, potential diseases, and even mental stress. HRV parameters are obtained with the use of beat-to-beat intervals (BBI). Conventional HRV monitoring systems such as ECG and PPG are contact sensors which has several disadvantages such as limited mobility, discomfort, skin irritation, and inability to measure through clothes or other obstacles. This study uses non-contact method of measurement that can possibly overcome these problems. This system uses a 24 GHz doppler radar for detection of chest wall displacement of the subject together with multiple signal processing techniques to extract the BBIs. With this, the quantitative values necessary for HRV analysis can be obtained to aid medical health personnel for diagnosis. Moreover, the system has a low mean relative error (MRE) and shows a high level of agreement between the extracted radar and reference PPG module data. Hence, the accuracy of this system shows its capability of determining HRV parameters using a non-contact method.
