A zigbee network-based multi-channel heart rate monitoring system for exercising rehabilitation patients

A zigbee network based wireless heart rate monitoring system for rehabilitation patients who are taking physical therapy inside a rehabilitation center is discussed in this paper. The main focus of this study is to develop an unconstrained monitoring system that can monitor patients' heart rates continuously so that it gives physical therapist early warning in real time if necessary. The whole system consists of the patient's side device (PSD) and central monitoring system (CMS) and they are linked via zigbee network. The PSD was designed to be wearable and consume minimum electrical power. Each PSD has its own identification number so that the CMS can monitor multiple numbers of patients simultaneously and generate a warning signal if necessary.
