A33 Development of Wearable Blood Pressure Sensor

Abstract

Blood pressure monitoring in daily life is important from a perspective of lifestyle-related diseases prevention. Conventional ambulatory blood pressure monitoring (ABPM) device can measure blood pressure at regular interval for 24 hours. However, it is limited by long measuring time, low sampling rate, and constrained posture. We developed a wearable sensor for monitoring a continuous blood pressure using the pulse wave velocity method. Results of exercise test by an ergometer show its effectiveness. A mobile software in a smart phone is in charge of controlling data acquisition, displaying general information and signals for real-time monitoring, and sending data to the database server. In this paper, we report sensor development and discuss pilot study results in a hospital.
