Background
Brain waves are electrophysiological phenomena reflecting brain neural activity, and the state of the body (e.g., tiredness, tension, relaxation, etc.) or diseases of the body (e.g., epilepsy, sleep disorders, depression, etc.) can be diagnosed and monitored by recording and analyzing brain electrical signals. The electroencephalogram measuring instrument is an electroencephalogram machine, wherein an electroencephalogram signal acquisition system is used as the most important component unit of the electroencephalogram machine, and is directly contacted with a body to acquire electroencephalogram signals.
The electroencephalogram signal acquisition system picks up electroencephalogram signals through electrodes, the electrodes are basically arranged on the head at present, are divided into 32-lead, 64-lead, 128-lead and the like according to the number of leads, the electrodes arranged behind the ears pick up the electroencephalogram signals of the temporal lobe of the brain close to the external auditory meatus, and the temporal lobe of the brain is responsible for processing auditory information and is also related to memory and emotion. In order to further explore the electroencephalogram signals of the temporal lobe of the brain close to the external auditory canal, the electrode should be arranged in the external auditory canal, however, the conventional electrode cannot be arranged in the external auditory canal by coating conductive paste, and therefore, an electrode capable of being arranged in the external auditory canal is needed.
