Abstract
A kind of dry electrode and its manufacture craft are the utility model is related to, the dry electrode prepared by the technique has low contact impedance and reliable signal transmission, can be easy to use by being connected directly detection bioelectrical signals with conducting wire.The problem of being not only restricted to that during traditional electrode detection bioelectrical signals electrolyte gel or cream need to be used.This dry electrode has good electric conductivity and wear-resisting anti-corrosion property by chemical method coating.Electrode shape is designed as ten pins or more pin, good with hair layer degrees of fusion, can improve detected person's comfort level.People are increasingly lifted to the attention rate of health in recent years, and the detection demand of bioelectrical signals can be stepped up, and this have satisfactory electrical conductivity and a wear-resisting anti-corrosion property, stable performance and can direct measurement bioelectrical signals dry electrode, have necessarily big market potential.
Description
Technical field
The present invention relates to a kind of dry electrode and its manufacture craft, this kind of dry electrode is without being used cooperatively electrolyte gel or cream
Bioelectrical signals can be directly gathered, eliminate the dependence of electrode pair conduction couplant in traditional biological electricity collecting work.
Background technology
Brain is the material base of all advanced behaviors of the mankind, human tissue cell always the moment spontaneously produce it is faint
Bioelectric, this bioelectric on relevant position can be recorded by the conductor being placed on scalp relevant position,
The figure of certain frequency, wave amplitude and position phase can be obtained after electroence phalograph amplifies, when pathological change occurs for brain tissue, figure
Shape also occurs to change accordingly, so as to provide foundation for diagnosis.It is this to be placed on scalp to export the conductor of electrical activity of brain
Referred to as electrode.
As the development of Neurology in recent years, electrode for encephalograms use are also more and more common.At present, it is normal that EEG signals are gathered
Electrode has many kinds, and most electrodes used are electrosilvering/silver chloride electrode and silver/silver chlorate of sintering in the market
Electrode.Electrode shape is mostly discoid to collect bioelectrical signals, it is necessary to be used together with electrolyte gel or cream.Discoid electricity
When in use, what is contacted with hair layer is electrolyte gel or cream, if electrolyte gel or cream apply uneven, is not had with hair layer for pole
There is contact completely or be not exposed to place position to be collected, collection deviation of signal can be made.And in the biological electricity of the collection more than two hours
Electrolyte gel or cream need to be supplemented during signal, can just remain valid collection.
The content of the invention
According to above-mentioned weak point, it is an object of the invention to provide a kind of circular dry electrode of pin, and the technical matters is easy,
Not high to equipment requirement, no stoichiometric is largely small, can all use this technique, passes through dry electrode made of the technique, good conductivity, essence
Degree is high, stable performance.It is no longer limited by electrolyte gel or cream, can direct measurement bioelectrical signals.It is provided by the invention dry
Electrode pin is soft, and electrode shape is designed as 30 pins, and this design is good with hair layer degrees of fusion, and overall contact area is big,
Wear comfortably, and signal use can be gathered for a long time.
To achieve the above object, technical program of the present invention lies in：A kind of dry electrode is provided, it be shaped as 30 draw
Pin, electrode use polyurethane material, and pin is soft, and electrode shape is designed as 30 pins, and distance is equal between adjacent leads, does electricity
Pole is that the surface of polyurethane material has stable conductive Ag/AgCl coatings.
Preferably：Preferably to reduce contact, increase contact area, it is ensured that low contact impedance and reliable signal pass
Defeated, electrode shape is designed as 30 pins, and this design is good with hair layer degrees of fusion, and overall contact area is big, between adjacent leads
Apart from equal, pressure is uniform when contacting hair layer, and detected person relatively has comfort level.
The present invention provides the production technology of above-mentioned dry electrode, and its making step is：
（1）Substrate plastic parts PU is put into aqueous isopropanol and cleaned.
（2）Substrate plastic parts PU after cleaning is put into methanol, silver nitrate, completes redox in sodium borohydride mixed liquor
Reaction.
（3）Above-mentioned reacted substrate is put into DEXTROSE ANHYDROUS, two citric acid monohydrate trisodiums, methanol, ammoniacal liquor, silver nitrate
Oxidation reaction is completed in solution.
（4）Cleaning is dried.
（5）Dry in an oven.
（6）Dry electrode is put into Iron(III) chloride hexahydrate, soaked in sodium chloride solution.
（7）Dry packing.
This preparation method is extremely convenient, changes traditional electrode using the constraint for needing adapted electrolyte gel or cream, is made
Dry electrode performance it is good.
Preferably：Substrate is put into aqueous isopropanol and cleaned, and can play and avoid other material disturbing reactions.
The beneficial effects of the present invention are：The present invention passes through the improvement to electrode production, dry electrode silver/silver chlorate of production
It is stronger attached power, is evenly distributed, coating is wear-resisting, conducts electricity very well.Production process is controllable, and raw material usage amount is thrown by reaction ratio
Enter, reduce production and waste.Production can be carried out by actual demand amount, and a large amount of productions provide needed for the batch production of brain electricity cap or small
Amount production is supplied to scientific research and testing to use.
The dry electrode produced by this preparation method, when in use can directly and skin contact, it is not necessary to adapted electrolytic gel
Or cream, worked so as to simplify acquiring biological electric signals.
Brief description of the drawings
Fig. 1 is the structure chart for the dry electrode that the embodiment of the present invention 1 is produced.
Fig. 2 is the potential measurement figure of dry electrode that the embodiment of the present invention 1 is produced in 0.9% sodium chloride solution.
Fig. 3 is the ac impedance measurement figure of dry electrode that the embodiment of the present invention 1 is produced in 0.9% sodium chloride solution.
Embodiment
With reference to specific embodiment, the present invention will be further described.
The various chemical reagent used in the embodiment of the present invention produce for Nanjing Chemistry Reagent Co., Ltd.
Example 1：By PU plastic substrates（30 pawls are taken to design）It is put into container bottle, adds after isopropanol cleans to take out and put
Enter silver nitrate with methanol by 1.8：Soaked in 1 solution prepared, after be put into methanol and sodium borohydride by 0.1：12 solution prepared
It is middle to complete reaction, then add DEXTROSE ANHYDROUS, two citric acid monohydrates after being put into silver nitrate by PU plastics and ammoniacal liquor is added dropwise in methanol
Trisodium, seal after methanol（Wherein DEXTROSE ANHYDROUS, two citric acid monohydrate sodium, silver nitrate, methanol in proportion 9.7：1.2：1.5：
45.6 prepare）.Take out to put after dry electrode clean dries and drying is completed at 170 DEG C of baking box, then dry electrode is put into six trichloride hydrates
Soak to take out to be put into sodium chloride solution afterwards in ferrous solution and soak.Take out after immersion and packed after drying.
