摘要

提出了一种低功耗、无线、实时、可穿戴的医疗保健系统,用于监测心电、脑电图和肌电信号等生物电位信号。该系统由模拟前端(AFE)、增量EδADC和短距离设备(SRD)收发器组成。所有ic均采用0.35μm CMOS技术实现,并集成在印刷电路板上。AFE和增量E/δADC功耗小于100μW,可配置不同的增益、带宽和采样率,在捕获不同的ExG信号时获得最佳的能量效率。锂电池为系统提供动力。该系统与华宏单片机相结合,通过无线通信将ExG信号实时还原到TFTLCD上,并将ExG信息存储在SD卡中,再将ExG数据传输到PC机,用MATLAB进行分析。

A low-power, wireless, real-time, wearable healthcare system
A low-power, wireless, real-time, wearable healthcare system for monitoring bio-potential signals including ECG, EEG and EMG signal is proposed. The system consists of Analog Front End (AFE), Incremental EδADC and Short Range Device (SRD) Transceiver. All the ICs are implemented in 0.35μm CMOS technology and integrated on the printed circuit board (PCB). The AFE and the Incremental E/δADC consume less than 100μW and can be configured to various gains, bandwidths and sampling rates for best energy efficiency when capturing different ExG signals. Lithium-battery provides power for the system. Integrating with Huahong MCU, the system is capable of restoring the ExG signals at real time on TFTLCD after wireless communication, storing the ExG information in SD card, and transferring the ExG data to PC for analyzing it in MATLAB.
