Blood pressure pulse wave measuring device with the function to reduce the influence of inertial force of body motion

Abstract

In this study, we report on a blood pressure pulse wave device with the function to reduce the influence of inertial force of body motion. The device consists of two force sensors which measuring blood pressure pulse wave and inertial force. We measured blood pressure pulse wave and inertial force by fabricated device during the body motion, and calibrated the blood pressure. We calculated the standard deviation of max value and amplitude of the blood pressure pulse wave. The standard deviation of amplitude decreased 57.8 % after calibration. Since the standard deviation of amplitude was decreased, we could reduce the influence of inertial force.
