The purpose of the present invention is to provide a garment-type electronic device capable of reducing discomfort during the wearing in the garment-type electronic device comprising an electrical wiring using stretchable conductor composition. In a part in contact with a body surface of a garment-type electronic device, a level difference at the boundary between the electrode portion where the conductor is exposed and the wiring portion covered with the insulating cover layer is substantially eliminated, whereby a garment type electronic device with a natural wearing feeling in which discomfort during wearing has been reduced is obtained. Furthermore, by providing the projections and the depressions in the fabric texture on its surface, a more natural wearing feeling is obtained. Such a garment-type electronic device can be produced by a printing transfer method.

Garment-type electronic device and method for producing same

A stretchable conductive sheet comprising a first insulating layer and a stretchable conductor layer provided on the first insulating layer, wherein the stretchable conductor layer has an electric resistance of 300 &#x3a9;/cm or less, and a load at stretching of a stretching rate of 10% of the conductive sheet is 100 N or less.

Stretchable electrode sheet and stretchable wiring sheet, and biological information measurement interface

An objective is to provide a stretchable conductor sheet which is useful as a material for electrical wiring and electrodes for garment-type electronic devices, the material having excellent durability in terms of washing and durability in terms of perspiration. A fabric provided with an electrode and an electrical wiring, which are formed from a stretchable conductor sheet, is obtained by: providing a film having 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.

Stretchable conductor sheet, stretchable conductor sheet having adhesiveness, and method for forming electrical wiring comprising stretchable conductor on fabric

A conductive fabric including a fabric and a wiring provided on the fabric, wherein the wiring has a first insulating layer formed on the fabric, a conductive layer provided on the first insulating layer, and a second insulating layer provided on the conductive layer, and wherein in a stretching test in which the conductive fabric is stretched by a stretching rate of 10% in a stepwise manner up to a stretching rate of 100% in a longitudinal direction of the wiring, a resistance change ratio when stretched at a stretching rate of 100% is 100-fold or less, the resistance change ratio when stretched at a stretching rate of 100% being represented by an equation: R/R(fold), where Ris a resistance value at a stretching rate of 0% and Ris a resistance value when stretched at a stretching rate of 100%. The conductive fabric is capable of maintaining high electrical conductivity even upon being stretched.

Conductive fabric

A method for preventing dozing off, comprising the steps of: a measurement step measuring human heartbeats; a decision step (Sto S) generating a trigger, hereinafter referred to as a 'drowsiness trigger', for indicating occurrence of drowsiness when a state in which a time interval between adjacent heartbeats, hereinafter referred to as a 'heartbeat interval', is longer than the previous heartbeat interval consecutively occurs; and a warning step (S) giving a warning to prevent dozing off when the drowsiness trigger is generated.
