상용 Force Sensitive Resistor(FSR)을 이용한 상완동맥에서의 인체 맥파 측정과 혈관의 긴장도, SDPTG Aging Index 분석 = An Analysis of Arterial Stiffness, SDPTG Aging Index through the Measurement of Physiological Pulse Signals from Brachial Artery using Commercial FSR

다국어 초록 (Multilingual Abstract)

This study conducted to confirm the possibility of pulse monitoring in the brachial artery through commercial FSR. The pulse from human body was measured by attaching FSR to the skin near the brachial artery and radial artery of the subject. For smooth measurement, the cylindrical structure was designed and attached to the FSR, and pulse signals measured from the brachial artery and the radial artery were compared each other. Using the relationship between the systolic peak and the diastolic peak of acquired pulse signals, the stiffness index(SI), which is reported to be related to the stiffness of blood vessel, was calculated. Also, the SDPTG aging index, which is proportional to the age of the subject, was calculated through five peak points obtained by second differentiation of the pulse signals. Pulse rate measured in the brachial artery and radial artery was similar at about 96 bpm, and the pulse signals measured at the two sites was clearly distinguishable. In addition, the SI and SDPTG aging indices were 6.81 m/s and -1.966, respectively, which were close to the normal range. Therefore, this study confirmed the possibility of pulse monitoring in the brachial artery through commercial FSR proposed. Subsequently, ths next studies should be conducted to derive statistical estimates from pulse data measured in several subjects.
