Title COMPOSITE MATERIAL AND COMPOSITE MATERIAL PRODUCTION METHOD
Abstract Provided are a composite material characterized by comprising a substrate, a porous body provided on the substrate and an insulating polymer extending, starting from a surface of the substrate, into the interior of the porous body, and a production method for said composite material.
Outline of related art and contending technology BACKGROUND ART
Medical diagnosis, as a method of treatment, using various devices, the heart, muscles, brain biopsy such as measurement of the electrical signal generated by the conductive, and the energization (electrical stimulation) by control of the biological function, a general already. With this technique, an electrode is part of the device, and the biological interface device.
Electrode is used in the medical field, in general, a metal or carbon conductive wiring, a conductive substrate material (such as plastic or glass) and configured. Here, the living organism and directly in contact with each electrode, and the necessity for a living body, used in such electronic equipment in recent years, there is room for improvement in this respect has been left in the.
Recently, hydrogel excellent biocompatibility substrate attracted attention and is the merit of using, as an electrode material is adhered to the hydrogel starts techniques have been developed.
The adhesive technology, hydrogels in a state of carrying the electrode material, by performing electrolytic polymerization of the conductive polymer, in the vicinity of the electrode material, electrode material from the surface by extending a conductive polymer, a technique of forming a conductive adhesive layer is known (see patent document 1 and non-patent document 1). In these documents, the hydrogel constituting the electrically conductive polymer and the polymer chains entanglement with each other, and the first electrode material can be adhered to the hydrogel have been reported.
