Abstract :
Unconstrained patients health monitoring systems are required in the field of medicine and nursing. Our developed ultrasonic oscillosensor can detect the vibration of human vital by setting to the under of the bed. This paper proposes an extraction method of the heart rate by using this sensor. Our method extracts the weakly detected heart pulse by enveloping the obtained data. Since our method employs fuzzy membership functions, it can adapt to extract the heart rate for various heart frequencies. As the result, we were able to successfully extract the heart rate for four volunteers.
