文章提出了一种基于自主芯片组的电生理眼镜，由信号采集模块、信号预处理模块、微控制器模块和信号分析模块组成。信号采集模块采用主动电极，因其高输入阻抗的特点，可以避免使用导电膏而提高系统实用性。信号预处理模块采用电生理模拟采集前端，对电生理信号进行滤波、放大，去除信号中的干扰，提高信号噪声比。微控制器模块采用意法半导体公司Cortex-M0处理器，主要实现电生理信号的模数转换、模拟前端设置、蓝牙模块收发控制。信号分析模块对电生理信号进行数字滤波、特征提取、心率监测。在此基础上，开展了针对颈部心电和脑机交互的实验并进行信号分析。

An electrophysiological glasses based on independent chipset was proposed. It consisted of signal acquisition module, signal preprocessing module, microcontroller module and signal analysis module. Due to the high input impedance, active electrode, instead of conductive paste, was used as signal acquisition module, which could improve system availability. The signal preprocessing module took advantage of electrophysiological analog front-end to filter and amplify electrophysiological signal, thus removed interference and enhanced the signal to noise ratio. Cortex-M0 processor of stmicroelectronics was adopted as the microcontroller module for analog-to-digital conversion, analog front-end setup, and controlling of bluetooth module transceiver. The signal analysis module could realize digital ifltering, feature extraction, and heart rate monitoring for electrophysiological signal. Based on this, experiments and signal analysis about neck electrocardiogram and brain electrical interaction were carried out.
