Abstract

This study introduces a portable multi-channel EEG signal acquisition system. The system is mainly composed of EEG electrode connector, signal conditioning circuit, EEG acquisition part, main control MCU and power supply part. The low-power EEG acquisition front-end ADS1299 and STM32 are used to form the signal acquisition and data communication part. The collected EEG signal can be transmitted to the PC for real-time display. After relevant tests, the system has small volume, low power consumption, high signal-to-noise ratio, and meets the requirements of portable wearable medical devices.

摘要

本研究介绍了一种便携式多通道脑电信号采集系统。该系统主要由脑电电极连接器、信号调理电路、脑电采集部分、主控制单片机和电源部分组成。采用低功耗脑电采集前端ADS1299和STM32构成信号采集与数据通信部分。采集到的脑电信号可传输至PC进行实时显示。经过相关测试，该系统体积小、功耗低、信噪比高，满足便携式可穿戴医疗设备的要求。
