Abstract
An apparatus for detecting vital functions of living bodies by means of electromagnetic signals includes a receiving device for electromagnetic signals. The receiving device for electromagnetic signals includes a device for obtaining frequency components that are characteristic of living bodies, out of received electromagnetic signals. The receiving device includes a direct demodulator that has a non-linear current/voltage characteristic that is frequency-selective for demodulation of frequency components that are characteristic of living bodies.
