発明の名称 (英語) METHOD FOR PRODUCING ELECTRODE ELEMENT, METHOD FOR PRODUCING ELECTRODE, AND MANUFACTURE OF MEASUREMENT SYSTEM USING SAID ELECTRODE
発明の概要(英語) The present invention addresses the problem of providing: a means for applying an electrically conductive polymer onto a base material directly and with high efficiency so that the electrically conductive polymer can be used as an electrode element without being bled when PEDOT-pTS is used as the electrically conductive polymer; a surface electrode which is produced without using an electrically conductive gel, has excellent electrical conduction performance and therefore can have a reduced surface area, can be adhered onto skin, does not undergo the displacement on skin even upon the application of a little movement of a body, and can be used in myoelectric signal measurement systems and brain wave measurement systems that have been used in various situations of life. Provided are: a method for producing an electrode element, said method being characterized in that a mixed solution of (1) an organic solvent-based solution containing an oxidative component and p-toluenesulfonate (pTS) and (2) 3,4-ethylenedioxythiophene (EDOT) is brought into contact with a base material to adhere the mixed solution onto the base material and then the contact part is subjected to a polymerization acceleration treatment in synchronization with the contacting; and a biopotential electrode to be applied onto a surface or to be punctured upon use, said biopotential electrode being characterized by comprising the electrode element.
従来技術、競合技術の概要(英語) BACKGROUND ART
The current, the metal such as copper electrically conductive carbon and the like of the present invention used in place of the conductive fibers, and the conductivity is superior in hydrophilicity, and, as a material having excellent compatibility with the living body the conductive polymer is drawing attention. This is because, metal and carbon is hydrophobic, yet rigid, bio-compatibility of the recognized problem in some cases. For example, in the case of using as an electrode on the surface of the living body, and the body surface of the biological electrode in order to ensure electrical continuity, a conductive paste is used between the body surface of the biological electrode must, stuffy feeling discomfort or irritation in the user by, contact dermatitis and further problems such as bacterial infections and has been indicated.
In this way to solve such a problem at the beginning is drawing attention as a material as a conductive polymer, and the already 'PEDOT-PSS(Poly(3,4-ethlenedioxythiophene) -polystyrenesulfonate) ' is provided, the conductive polymer, biological material such as silk fibers of the conductive fibers of the coating, has been developed by the present inventors (for example, Patent Document 1, 2, Non-Patent Document 1).
That uses a conductive polymer as an application of the electrode, the biological electrode is used and the electromyographic or an electroencephalograph.
Walks the human or the animal when the moving vehicle, that is the basis that the driving force is produced by the muscle contraction. Such a method of knowing the activity state of the muscles, the muscles (Electromyography: EMG) as the control. Is a projection of muscles, neuromuscular disease and the needle electromyogram to be used in the clinical diagnosis, the surface electromyogram used to analyze the operation of the two halves.
The needle electromyogram of the former, increasingly complex neuromuscular disease in modern society is increasingly being required. In the latter the surface electromyogram, the muscle action potential of the surface of the living body is derived through an electrode, it can be visualized as a electromyogram, to correspond to an operation, a time at which the muscle which, whether the degree of activity can be known.
In recent years, an electromyogram and the myoelectric potential measurement system is provided, the cost performance and the device, including the software to improve the user-friendlier, myoelectric potential measurement itself is becoming more easily than the prior art. In addition, general-purpose signal processing software using a personal computer by using various signal processing modules can be easily performed.
As a result, in particular surface electromyography in the measurement system, in the field of rehabilitation or sports motion analysis discussed actively apparatus has been effectively used.
With respect to the EEG, as well as a test at the medical institution, home testing, remote medical care, psychological study, care welfare field, ubiquitous health care system, such as BCI (brain computer interface) an important position in the emerging.
In such a situation, the situation in which a more general life in a subject brain wave measurement of physical, psychological without burdening the means for performing an EEG measurement is demanded.
In addition, to correlate eye movement and brain waves, eye movement and brain wave synchronized with the action potential can be provided by the composite system.
