Abstract

The human pulse wave is a vital biosignal that includes the diagnostic data related with the heart and the cardiovascular system of human body. Based on the mechanical transducing method, a pulse detection transducer using optical fiber was developed to acquire the pulses non-invasively. To improve the detection efficiency, we proposed a new design that consists of two combinational parts; detecting part, which is in contact with the pulsating skin and transmits the displacement motion of the pulsating skin to the sensing part, and sensing part, which converts the physical quantity transmitted from the detecting part to electronic signal. By using the new method, we confirmed that the proposed sensor can detect the C point(incisura) and the T wave(tidal wave) which is not easily detected by existing transducers, and showed that the three signals of ECG, pulse, and differential pulse displayed on the PC monitor screen to recognize the feature points of pulse.
