| Abstract: | AIM To study the technology and method of non-contact detection of breathing and heartbeat of human body. METHODS In experimental study, low-intensity millimeter wave with 8 mm wavelength was used, based on Doppler rada principle and technology of biomedical signal processing. RESULTS On the conditions of the illuminate power P<1 mW and the distance s<5 m, the breathing and heartbeat could be measured in different positions, from different wave beam angles and with different clothing on the subject without contact. CONCLUSION This technology and method is high sensitive, harmless to the health and with low-intensity. It is a practicable technology and method of non-contact detection for breathing and heartbeat of the human body. |
