| 摘 要： | 本研究设计了一种高精度可穿戴心电采集系统,该系统由心电模拟前端电路、数字滤波及控制电路和系统软件三部分组成.其采用软硬件滤波来消除基线漂移、皮肤接触噪声及运动伪迹等干扰,并设计嵌入聚吡咯织物电极的心电衣来增加穿戴舒适性.经与两款同类型心电监护仪相比,结果表明:本系统准确度较高,功耗较低,且能稳定可靠的对心电进行长时间监测,并能通过蓝牙实现无线传输.

| Abstract: | An improved high precision wearable ECG monitoring system was designed, which consisted of three parts: (1) ECG analog front end (AFE), (2) digital signal processing and micro-control circuits, (3) system software.Besides, several hardware/software filtering methods were taken to eliminate the baseline wander, skin contact noise and motion artifacts, furthermore, three flexible polypyrrole textile electrodes embedded into a sweatshirt were used to enhance comfort and conductivity.And a comparative study had also been carried out to show the performance and accuracy with two similar ECG apparatuses.The experimental results demonstrate that our ECG monitoring system can continuously and stably measure heart rate accurately for a long time, and can also be wireless transmitted data via bluetooth, which indicates it is an effective solution for continuously monitoring in the ubiquitous healthcare environment for preventing chronic heart disease. |
