这项工作描述了一个便携式无处不在的医疗保健应用的生物电位采集系统，使用灵活的聚二甲基硅氧烷干电极（FPDE）和低功耗的记录电路。这种新型的FPDE使用Au作为皮肤接触层，这是使用CO2激光和复制方法技术。FPDE是从商业生物电位电极修改而来的，其具有使用干电极而不是湿电极的导电卡扣，其提出了用于测量目的的可靠和坚固的附接，并且附接尼龙搭扣使其可穿戴在前臂上用于生物电位应用。此外，本研究提出了一种记录设备来存储生物电位信号数据，并提供了便携性和低功耗的建议采集系统。为了获取差分生物电位，例如心电图（ECG）信号，所提出的记录设备包括使用互补金属氧化物半导体（CMOS）工艺制造的低功耗前端采集芯片、商用微控制器（MSP430F149）和用于便携式医疗保健应用的安全数字（SD）卡。该系统能够有效地获取心电信号，并且对皮肤舒适。该系统的功耗约为85毫瓦的连续工作超过3天的时间与两个AA电池。它也可用作紧凑型霍尔特心电图系统。
This work describes a bio-potential acquisition system for portable ubiquitous healthcare applications using flexible polydimethylsiloxane dry electrodes (FPDEs) and a low-power recording circuit. This novel FPDE used Au as the skin contact layer, which was made using a CO2 laser and replica method technology. The FPDE was revised from a commercial bio-potential electrode with a conductive snap using dry electrodes rather than wet electrodes that proposed reliable and robust attachment for the purpose of measurement, and attaching velcro made it wearable on the forearm for bio-potential applications. Furthermore, this study proposes a recording device to store bio-potential signal data and provides portability and low-power consumption for the proposed acquisition system. To acquire differential bio-potentials, such as electrocardiogram (ECG) signals, the proposed recording device includes a low-power front-end acquisition chip fabricated using a complementary metal-oxide-semiconductor (CMOS) process, a commercial microcontroller (MSP430F149), and a secure digital (SD) card for portable healthcare applications. The proposed system can obtain ECG signals efficiently and are comfortable to the skin. The power consumption of the system is about 85 mW for continuous working over a 3 day period with two AA batteries. It can also be used as a compact Holter ECG system.
