Modern microwave Doppler radar-based physiological sensing is playing an important role in healthcare applications and during the last decade, there has been a significant advancement in this non-contact respiration sensing technology. The advantages of contactless, unobtrusive respiration monitoring have drawn interest in various medical applications such as sleep apnea, sudden infant death syndromes (SIDS), remote respiratory monitoring of burn victims, and COVID patients. This paper provides a perspective on recent advances in biomedical and healthcare applications of Doppler radar that can detect the tiny movement of the chest surfaces to extract heartbeat and respiration and its associated different vital signs parameters (tidal volume, heart rate variability (HRV), and so on) of the human subject. Additionally, it also highlights the challenges, and opportunities of this remote physiological sensing technology and several future research directions will be laid out to deploy this sensor technology in our day-to-day life.
基于现代微波多普勒雷达的生理传感技术在医疗保健应用中发挥着重要作用，在过去十年中，这种非接触式呼吸传感技术取得了重大进展。非接触式、不干扰的呼吸监测优势引发了人们对各种医疗应用的兴趣，如睡眠呼吸暂停、婴儿猝死综合征（SIDS）、烧伤患者的远程呼吸监测以及新冠患者的监测。本文阐述了多普勒雷达在生物医学和医疗保健应用方面的最新进展，该雷达能够检测胸部表面的微小运动，以提取人体的心跳、呼吸及其相关的不同生命体征参数（潮气量、心率变异性（HRV）等）。此外，还强调了这种远程生理传感技术面临的挑战和机遇，并将列出几个未来的研究方向，以便在日常生活中部署这种传感器技术。
