Abstract

We present a new type of sensor for vital signs monitoring. The primary advantages of the millimeter-wave radar are ability to operate remotely, without electrodes or wires and through any clothing or fur. Since radar carrier wavelength is about 3 mm, we achieve significant noise immunity, sensitivity and accuracy. Thus it is not only detector, but a powerful tool for exploring heart and respiration mechanics. Series of lab tests with animals (rat, rabbit) and human were carried out. Experimental human heartbeat measurement data for monitoring distance of 2 meters is shown and compared to data from a commercial portable ECG device.

用于生命体征监测的毫米波雷达
我们提出了一种新型的生命体征监测传感器。毫米波雷达的主要优点是能够远程操作,不需要电极或电线,也不需要穿任何衣服或毛皮。由于雷达载波波长约为3mm,我们实现了显著的抗干扰性,灵敏度和精度。因此,它不仅是探测器,而且是探索心脏和呼吸力学的有力工具。在动物(大鼠、兔)和人身上进行了一系列的实验室试验。图中显示了监测距离为2米的实验人类心跳测量数据,并与商用便携式心电图设备的数据进行了比较。
