Description

Technical Field

[0001] The utility model relates to the field of a fixed installation structure for an electroencephalogram sensor, in particular to a fixed connection device for an electroencephalogram sensor. Background Art

[0002] Brain waves are the result of the sum of the postsynaptic potentials of a large number of neurons in the cerebral cortex. When detecting changes in human brain waves, a special EEG sensor needs to be fixed on the head of the person being tested for detection. A fixed connecting device is required for fixation. Traditional fixed connecting devices are mostly headbands. The EEG sensor is fixedly installed on the headband through a fixing part. There are still certain problems in its use. For example, the traditional EEG sensor is fixedly installed on the headband through a fixing part. The position on the headband is fixed and cannot be adjusted. In other words, the position on the user's head cannot be adjusted according to needs, resulting in a poor EEG sensing effect. At the same time, the traditional EEG sensor is fixedly installed on the headband, and the common method is to glue it, which is relatively troublesome during installation and removal.
