The EEG signals of ionic species conduction are converted into the EEG signals electronically conducted in electronic system, so as to realize brain telecommunications
Number collection.Electrode plays pivotal player in eeg signal acquisition, and its performance indications has to whole brain machine interface system
The influence of restriction.Existing conventional wet silver/silver chlorate brain fax sense electrode is primarily present following both sides problem：1) it is continuous
Use time is short.Influenceed by scalp, scalp oiliness secretion and many factors such as electrode and scalp contact condition, scalp
Often there is larger impedance between electrode so that the signal noise detected is larger, and wave distortion is serious.Therefore needed before use
Conductive paste is injected on electrode, electrode impedance is reduced.But the conduction liquid or conductive paste used by it can be by body temperature
And environment temperature influence and constantly evaporate exsiccation so that electrode impedance increases therewith, EEG signals quality will decline, more sternly

Put smearing conductive paste.It is even more important therefore, a kind of new brain fax sense electrode device of research seems.For conventional brain fax electrification
The problems of pole, numerous area research mechanism scientific research personnel expand further investigation from different technological approaches.There is section
The personnel of grinding propose the dry electrode contacted with the pure dryness of skin, solve that continuous use time is short or set-up procedure challenge,
But electrode impedance is too high.Also scientific research personnel proposes the moist electrode based on conduction liquid, solves that continuous use time is short or standard
Standby process challenge, but its motion artifacts is too high.Therefore need a kind of low artefact, low impedance characteristic can for a long time continuously make
New brain fax sense electrode device, to lift the signal quality of brain wave acquisition.
