Stretchable conductor sheet, stretchable conductor sheet having adhesiveness, and method for forming wiring line formed of stretchable conductor on fabric

Abstract

To provide a stretchable conductor sheet which is useful as a material for electrical wiring lines and electrodes for wearable electronic devices, said material having excellent durability in terms ofwashing and durability in terms of perspiration. A fabric provided with an electrode and an electrical wiring line, which are formed from a stretchable conductor sheet, is obtained by: providing a film having mold releasability with a first stretchable conductor layer which is formed from a paste material that uses carbon-based particles as a conductive filler, while using a flexible resin as a binder resin; subsequently forming a second stretchable conductor layer, while using metal-based particles as a conductive filler; laminating a hot melt adhesive layer thereon; superposing the resulting laminate on a fabric after removing unnecessary parts from the laminate by means of partial slits; and subjecting the resulting fabric to hot pressing. Since the carbon-based particles adsorb a contamination substance of the metal-based particles, oxidation degradation and sulfuration degradation of the metal-based particles is reduced, thereby improving the durability.

Description

Technical field [0001] The present invention relates to a sheet-like stretchable conductor sheet that can be laminated on a stretchable base material, and a method for forming electrical wiring used in clothing-type electronic devices and the like using these. Background technique [0002] In recent years, wearable electronic devices have been developed that aim to enable electronic devices with input and output, computing, and communication functions to be used in close proximity or in close contact with the body. As wearable electronic devices, there are known accessory-type devices such as watches, glasses, and earphones, and textile-integrated clothing-type electronic devices in which electronic functions are assembled on clothing. [0003] Electronic equipment requires electrical wiring for power supply or signal transmission. Especially for textile-integrated wearable electronic devices with stretchable clothes, the electrical wiring is also required to be stretchable. Gene...
