Low-Power Wireless Wearable ECG Monitoring System Based on BMD101

Abstract

Cardiovascular disease (CVD) threats people's health heavily and long-term electrocardiogram (ECG) monitoring is of great meaning for better treatment. To realize the remote long-term ECG monitoring, a low-power wireless wearable ECG monitoring system is proposed in this paper. The wearable telemetry ECG monitoring system includes three parts, respectively, ECG monitoring device, mobile phone, and the cloud server. The ECG monitoring device, abbreviated as ECGM, is designed based on BMD101 sensor chip and CC2640R2F wireless MCU. The ECGM collects ECG signals from the fabric electrodes adhered to users' chest, preprocesses the signal to eliminate the injected noise, and then sends the digital output data to users' hand-held mobile phones through Bluetooth low energy (BLE). The phones are in charge of ECG classification and uploading both original and processed ECG data to the cloud server. The cloud server stores users' ECG data, accounts for huge calculation in ECG processing & diagnosing, and provides telemetry monitoring service for cardiologists. Users, namely patients, view ECG on their phones and acquire treatment advices from both machine and cardiologists. The novelty of the system lie in the combination of low-power ECG sensor chip and BLE chip, and thereby it features ultra-low power consumption and high signal quality.
