Research and realization of blood pressure monitoring system based on ZigBee wireless sensor network

Abstract

Aiming at disadvantages of independent measuring of conventional blood pressure monitoring instruments and unfavorable centralized monitoring, this paper studies and puts forward a design of blood pressure monitoring system based on ZigBee wireless sensor network, using normalizing method to improve conventional amplitude coefficient method, and increasing measure precision. The experimental results indicate that the system can real-timely monitor human blood pressure, sensor node collects data accurately, data is transmitted reliably via wireless sensor network, and remote monitoring can be realized. © 2012 Springer-Verlag.
