【摘要】 脑电采集装置在脑电睡眠监测系统中起着关键作用,针对目前脑电采集装置存在体积庞大,价格昂贵的现状,设计了一套体积小,功耗低,便于佩戴的脑电采集装置。应用ADS1299脑电采集芯片设计了脑电采集装置的电路及相应的控制程序,并用该装置采集受试者的脑电信号,将脑电信号导入Matlab做处理和显示。实验结果表明该装置可以采集到人体脑电信号,可用于睡眠监测系统的脑电采集。更多还原

【Abstract】 Electroencephalography( EEG) acquisition device plays a key role in the design of sleep monitoring system based on the EEG. At present,the EEG acquisition device is huge and expensive. This paper designed a low-power portable and wearable EEC acquisition device. Firstly,the hardware circuit of EEG acquisition device was designed based on ADS1299 EEG acquisition chip and then the corresponding control program was designed. At last,the EEG signal was collected by the device and input into Matlab to process and display. The result of experiment shows that the equipment can collect EEG signals,hence it can be applied in EEG acquisition of sleep monitoring system.更多还原
