Implementation of a Wireless Sensor Network for Heart Rate Monitoring in a Senior Center

Abstract

Objective: Wearable sensor systems are widely used to monitor vital sign in hospitals, and in recent years have also been used at home. In this paper we present a system that includes a ring probe, sensor, radio, and the receiver, designed for use as a long term heart rate monitoring system in a senior center. The primary contribution of this paper is successfully implementing a cheap, large scale wireless heart rate monitoring system that is stable and comfortable to use 24 hours a day. Materials and Methods: We developed new finger ring sensors for comfortable continuous wearing experience, and used dynamic power adjustment on the ring so the sensor can detect pulses at different strength levels. Result: Our system has been deployed in a senior center since May 2012, and 63 seniors have used this system in this period. During the 54 hours system observation period, 10 alarms were set off. 8 of them are due to abnormal heart rate, and 2 of them loose probes. The monitoring system runs stably with the senior center’s existing Wi-Fi network, and achieves 99.48% system availability. The managers and caregivers use our system as a reliable warning system for clinical deterioration.

Conclusion: The results of the year-long deployment show that the wireless group heart rate monitoring system developed in this work is viable for use within a designated area.
