Technology for non-contact measurement of vital signs (i.e., heartbeat, respiration, and body temperature) has attracted significant attention as these physiological parameters are important for understanding health states. Recently, novel bio-sensors have been developed, such as microwave medical radar, thermography, RGB cameras, and ToF sensors have also been published. These sensors can be classified into image-based (including RGB, infrared, and ToF), piezoelectric ballistocardiogram (BCG)-based, and medical radar-based sensors. For example, RGB and infrared thermography image-based technologies detect minute skin-color variations in RGB images caused by blood circulation to extract heartbeat and temperature variations around nasal areas in thermal images to determine respiration. The mechanical vibration induced on the chest surface by heartbeat and breathing can be captured by piezoelectric sensors that produce electrical signals by the piezoelectric effect. Similarly, medical radar measures the Doppler shift or phase shift caused by the periodic vibration of the chest surface. These sensors have wide-ranging clinical applications, including in systems for home healthcare monitoring, identification of sleep apnea, detection of infectious disease, and measurement of stress levels. These sensors show high potential for a wide range of medical applications. However, it requires advanced signal processing techniques for denoising processes, extracting physiological signals, and estimating physiological parameters. This session aims to provide recent topics in this field, and highlight the latest state-of-the-art biosignal processing method for detection of physiological signals.
