Abstract:: A designing scheme of a portable electroencephalogram (EEG) detection device based on ADS1299 is introduced in the study. The proposed device is designed with the integrated analog front-end chips of ADS1299 to collect EEG signals. A low-power consumption module of Bluetooth 4.0 is used to achieve wireless data transmission. Moreover, a low-power consumption ferromagnetic memory MCU is combined with a power management module to reduce power consumption effectively. Finally, the waveform display and analysis of EEG signals are carried out by Matlab GUI. The test of intrinsic parameter proved that the proposed device which has the characteristics of small size, low noise and low-power consumption can achieve long-time and high-precision acquisition of EEG signals.
