本文研究了利用电磁耦合对人体组织进行非接触心肺活动监测的方法。结合了两种测量方式：基于磁涡流感应的电感耦合传感器和基于位移电流感应的电容式耦合传感器。对于电感和电容耦合路径，从理论和实验上分析了该系统对电组织特性的敏感性及其对运动的依赖性。实验室实验验证了这两种耦合方法在评估呼吸和脉搏无接触和最小胸壁运动方面的潜力。示威者被嵌在椅子上，以便能够从胸部后部进行记录。
In this paper, the method of noncontact monitoring of cardiorespiratory activity by electromagnetic coupling with human tissue is investigated. Two measurement modalities were joined: an inductive coupling sensor based on magnetic eddy current induction and a capacitive coupling sensor based on displacement current induction. The system's sensitivity to electric tissue properties and its dependence on motion are analyzed theoretically as well as experimentally for the inductive and capacitive coupling path. The potential of both coupling methods to assess respiration and pulse without contact and a minimum of thoracic wall motion was verified by laboratory experiments. The demonstrator was embedded in a chair to enable recording from the back part of the thorax.
