Replaceable electrode brainwave telemeter

This creation is about a brainwave telemeter, especially a replaceable electrode brainwave telemeter that can replace the appropriate electrode according to different parts of the test.

Everyone, every day, every second, no matter what they do, or even when they sleep, our brains will produce "current pulses" from time to time. These currents generated by the brain are called "brains".

In general, brain waves are divided into four categories according to their frequency: β wave (consciousness), alpha wave (bridge of consciousness and subconsciousness), θ wave (subconscious) and delta wave (unconscious). Formed a person's internal and external behavior and performance in learning. In modern computer technology, our brainwaves can be clearly displayed on the computer screen through the "brain wave measuring machine".

At present, the measurement of brainwave recording can be divided into two types. One is the electroencephalogram (EEG), which measures the current in the cerebral cortex. The current in the cerebral cortex is the current that occurs outside the cell, and is composed of the cell population and other cell populations. The potential difference between them is formed. The other is magnetoencephalographic (MEG), which is based on Faraday's law - electromagnetism. When the brain nerve is activated, the electrical signal will cause a change in the magnetic field. The size of the detected signal is the brain magnetic wave.

In general, in the brain wave measurement process, a padded wet electrode is used, and the subject is operated in a sleep state, which can not only be used to record changes in brain wave signals in a certain period of time, but also Further analysis is used to understand the depth of sleep changes, playing a key role in sleep examination. However, it is worth noting that when the site to be tested changes, for example, when the site to be tested is the top of the head, the back of the brain, etc., the wet electrode is not applicable, so that the application of the brain wave measuring machine The scope is greatly limited.

Secondly, in the examination during sleep, the primary task is the comfort of the subject, and the subject must be kept in a good and comfortable sleeping environment before the brain wave measurement procedure can be performed.
