Portable 32-Channel Wireless EEG Acquisition Device

With the continuous development of modern low-power embedded systems and brain-computer interface technology, research on portable high-precision EEG acquisition devices has gained widespread attention. However, existing EEG acquisition devices generally suffer from bulky sizes, excessive power consumption, and high costs. These shortcomings prevent traditional devices from effectively meeting the emerging demands for high precision, low latency, and stable wireless transmission in scenarios such as home health monitoring, neurofeedback training, and brain-computer interface research. Thus, there is a pressing need for the development of a low-cost, low-power, and high-channel-count portable EEG acquisition system featuring high-precision signal acquisition, adaptive interference cancellation algorithms, and stable wireless transmission technologies to overcome the limitations of traditional equipment.
