Preferably: directly gather bioelectrical signals, do not need to use conductive paste or conductive liquid.
Present invention also offers the preparation method of brain electricity elasticity dry type soft electrode, its preparation process is as follows:
(1), designing mould, die trial as required.
(2), sheet metal together with wire bonds, be placed on inside the mould that designs, conducting polymer composite be placed in mould and be injection molded into elasticity dry type soft electrode.
(3), in elasticity dry type soft electrode contact dip in the ink-like Ag/AgCl electrocondution slurry that oils, then sinter 30 minutes through low temperature (90 ~ 120 DEG C).
(4), with standard salt acid treatment electrode surface.
Wherein Ag/AgCl electrocondution slurry be manufactured with following step:
prepare silver/silver chloride powder, 200 object argentum powder and chlorination argentum powder, 10:1 mixing in mass ratio, with ball mill ball milling 10 hours, mixes argentum powder fully with chlorination argentum powder
in the powder of mix homogeneously, add binding agent, fully after mixing, add diluent, silver-colored silver chloride powder: binding agent: the mass ratio of diluent is 1:1:1
be placed on by mixed raw material in Achates tank, ball mill ball milling 10 hours, the slurry making ink-like is for subsequent use.
Beneficial effect of the present invention is:
1, silver-colored silver chloride powder is classical electrode material, and the EEG signals of collection accurately, reliably.
2, this electrode does not need to thrust scalp horny layer, brings sensation of pricking can not to patient or experimenter, can not cause infection yet.
When 3, using this electrode to gather bioelectrical signals, do not need to use conductive paste or conductive liquid.Save the time of health care worker, after inspection, patient or subjects skin do not have conductive paste to remain, does not need cleaning.
4, electrode is soft, and comfortableness is good.Elasticity dry type soft electrode is elastic conduction macromolecular material, this material softness, patient or subject wears comfortable, without constriction.
5, structural design cleverly.Skeleton electrode structural design, is more conducive to the contact of electrode and scalp.Especially the long patient of hair or experimenter is applicable to.
