[0002] The electroencephalogram (EEG) cap is an important tool for recording EEGs. It is mainly composed of electrodes and fixing devices made of conductive materials. The EEG cap can accurately detect and record the electrical activity of the brain, which helps to diagnose a variety of neurological diseases such as epilepsy, encephalitis, brain tumors, etc.

The controller includes a circuit board, a digital signal processing module, a cache module, a Bluetooth module, and a USB interface chip. The cache module and the USB interface chip are electrically connected to a computer. Signals collected by the electrodes pass through the digital signal processing module and the cache module in sequence before being sent to the computer via the Bluetooth module. When no Bluetooth connection is available, the collected signals are first stored in the cache module and then transmitted to the computer via the USB interface chip. The electrodes of this EEG cap are easy to assemble and disassemble, and the controller is conveniently connected to the computer via Bluetooth.
