Abstract

The ever-increasing pace of development of high-frequency sources is opening new vistas in the field of remote physiological sensing. In this work, we report the successful detection of the heart beat in the reflection coefficient of human skin, monitored at 303 and 404 GHz. The measurement was taken at a distance of 72 cm and the beam was focused on the hand palm. The results demonstrate a high correlation with the heart beat extracted from a concurrent ECG measurement. Furthermore, these frequencies demonstrate a good capability to follow phasic changes in the heart rate.
