Portable EEG Acquisition System Based on Pre-Gelled Electrodes
A portable EEG acquisition system based on pre-gelled electrodes is designed for addressing the problems of existing EEG acquisition systems such as high cost,cumbersome use of equipment and poor wearing experience.The EEG acquisition system collects scalp EEG signals through pre-gelled electrodes,uses an ADS1299 integrated chip as the analog-to-digital converter,and connects to the host computer through a wireless connection.Experiments show that the EEG acquisition system can effectively acquire scalp EEG data with significant signal characteristics,the device is easy to use and comfortable to wear which can meet the needs of brain-computer interface related experiments.
