A low-cost (440.56 CNY), small-sized, wireless, high-precision, low-power consumption 4-channel EEG measurement system (NeuroVista) for frontal area EEG measurements, which can be used with the Oculus Quest 2, enabling EEG measurements in VR environments. The system has an input-referred noise of less than 2.22 μ Vrms, a common mode rejection ratio of over 88dB, a measurement resolution of less than 0.1μ Vrms, works at a sampling rate of 250Hz, and supports metal dry electrodes. It includes a built-in analog bandpass filter, right-leg drive circuit, and notch digital notch filter, which can significantly reduce noise during measurement.
