A Heart Pulse Monitoring System by Air Pressure and Ultrasonic Sensor Systems

Abstract

This paper describes a heart pulse monitoring system by both air pressure sensor and ultrasonic sensor systems. Our developed ultrasonic oscillosensor system can obtain the heart pulse information of human by setting to the under of the bed. Our developed air pressure sensor system can also detect a pressure change of vital information and a heart pulse by setting into the mattress on the bed. The air pressure sensor could detect the heart pulse at higher accuracy. However, it depends on the position of the senor in the bed. A system of the two sensor systems can complementary provides the heart pulse with high accuracy and robustness.
