Title ELECTRONIC FUNCTIONAL MEMBER, ELECTRONIC COMPONENT, AND WEARABLE DEVICE
Abstract The electronic functional member according to the present embodiment is provided with: a base material; a fiber net made of a fibrous resin composition that extends over the base material so as to be connected thereto; and a patterned conductive covering part that covers one surface side of a portion of the fiber net and that extends over the base material.
Outline of related art and contending technology BACKGROUND ART
In recent years, flexible electronics, soft material has a wide variety of applications from the application, a high attention. Among them, with the aging of the social world, which are of interest to the health care field. For example, by mounting to the surface of the human body or in vivo, directly from cells and tissues as a means for obtaining the biometric information has attracted attention.
In general, flexible electronics, flexible electronics device on a substrate fabricated of a form, the flexibility is not sufficient. Therefore, the tracking surface is not sufficient, a high degree of accuracy and to obtain information such as an uncomfortable feeling at the time of installing can not be sufficiently reduced.
In order to solve such a problem, an elastic holding part for the living body detection unit are included in the disclosed electrode (for example, Patent Document 1). This biomedical electrode is, the living body when the contact detection unit, detection unit including the holding portion having elasticity. Therefore, in response to the pressure retaining part is deformed and, increasingly follow the surface of the detector.
In addition, the measured myoelectric potential braided wiring (for example, Patent Document 2) for arm cover textile or cloth at a constant interval to the conductive fibers are braided metal plating of the contact line (for example, Patent Document 3) the working electrode is also disclosed. In Patent Document 2, the wiring itself in the weave from each other, the rigidity of the wiring is reduced one by one, the surface follow-up property is enhanced. Patent Document 3 is, in the textile fabric of woven fibers can be metal, the surface follow-up property is enhanced.
In addition, hydroentangling the nonwoven fabric on a flexible insulating synthetic resin film is attached to the body of the thin electrode is also disclosed (for example, Patent Document 4). In this method, a water non-woven fabric using a high deformability, surface tracking is enhanced.
Non-Patent Document 1 is 2 and further, the metal nanowires on a substrate by coating the surface of the electrode having the high follow-up property is disclosed.
