[0002] EEG monitors can record the electrical activity of the brain and generate electroencephalograms (EEGs). Doctors can diagnose various brain diseases, such as epilepsy, brain injury, and cerebrovascular disease, by analyzing the characteristics and patterns of the EEGs.

[0003] Brain waves are the basic theoretical research of brain science, and brain wave monitoring is widely used in its clinical practice. Brain wave detectors are usually used for brain wave monitoring. The detection units of the brain wave detectors in the prior art are mostly fixed on the instrument. When it is attached to the head for detection, the position of the detection unit is relatively fixed, resulting in a single detection orientation, which makes it easy for large errors to occur in the detection data and is not practical enough. Therefore, it is necessary to redesign a brain wave detector that can detect in multiple directions to address the above problems. Utility Model Content
