Abstract
Official abstract text for this publication.
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 100 /R 0 (fold), where R 0 is a resistance value at a stretching rate of 0% and R 100 is 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A conductive fabric comprising a fabric and a wiring provided on the fabric, wherein the wiring comprises 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, wherein the conductive layer comprises a conductive filler and a resin, wherein the fabric is a woven fabric, a knitted fabric, or a nonwoven fabric, 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 100 /R 0 (fold), where R 0 is a resistance value at a stretching rate of 0% and R 100 is a resistance value when stretched at a stretching rate of 100%. 2. The conductive fabric according to claim 1 , wherein when the number of tests in which a break in electrical continuity occurs when the stretching test is performed 10 times is represented by an alphabet “a”, a defective rate represented by an equation: (a/10)×100(%) is 30% or less. 3. A wearable biological information measurement device produced using the conductive fabric according to claim 1 . 4. The wearable biological information measurement device according to claim 3 comprising measurement means for measuring biological information of a wearer and a mechanism for analyzing the measured biological information. 5. The conductive fabric according to claim 1 , wherein the fabric is a knitted fabric.
