Contactless Heart Monitoring (CHM)

An apparatus for measuring mechanical heart movement, and heart rate monitoring without physically connecting electrodes or other sensors to the body was developed. Contactless heart monitoring (CHM) based on Doppler radar with frequency of 2.4 GHz at a distance of up to 30 cm is capable of detecting the mechanical vibrations of the heart, without any contact with the person's body, and it can operate and record the heart rate through a mattress, wall or other barriers. In this paper we present the theory, and preliminary results of our basic CHM setup.
