Abstract

Ahstract-This paper presents a non-contact beat-to-beat blood pressure (BP) measurement system using a continuous wave (CW) Doppler radar. The tiny displacement on body surface induced by the central aortic artery is acquired by a digital-IF CW Doppler radar. Then the pulse transit time (PTT) is extracted to calculate the BP. Experiments have been carried out with three human subjects to evaluate the performance. Compared with the sphygmomanometry, the results demonstrate that the proposed system can acquire the beat-to-beat BP accurately.
