Abstract
Official abstract text for this publication.
Provided is a stretchable electrode which has excellent flexibility, stretchability and electrical conductivity and is capable of suppressing increase of the electric resistance in being elongated and the occurrence of variation in the electric resistance during repeated stretching and contracting. The stretchable electrode of the present invention comprises a base formed of an elastomer composition and an electrode main body integrated with the base, wherein the electrode main body is formed using multi-walled carbon nanotubes having a fiber length of 50 μm or more.
First claim
Opening claim text (preview).
1 . A stretchable electrode comprising a base formed of an elastomer composition and an electrode main body integrated with the base, wherein the electrode main body is formed using multi-walled carbon nanotubes having a fiber length of 50 μm or more. 2 . The stretchable electrode according to claim 1 , wherein the multi-walled carbon nanotube has a fiber diameter of 5 to 30 nm. 3 . The stretchable electrode according to claim 1 , wherein the stretchable electrode is used for a sensor sheet. 4 . A sensor sheet using the stretchable electrode according to claim 1 , wherein the base is sheet-like and the electrode main body is disposed on both surfaces of the base, and the electrode main body disposed on one surface of the base and the electrode main body disposed on the other surface of the base are at least partially opposed to each other with the base interposed therebetween. 5 . The sensor sheet according to claim 4 , wherein the electrode main body is rectangular and plural rows of the electrode main bodies are disposed on both surfaces of the base. 6 . A capacitive sensor comprising the sensor sheet according to claim 4 , a measurement instrument, and external conducting wires for connecting between the measurement instrument and electrode main bodies which the sensor sheet includes, wherein a portion in which the electrode main body disposed on one surface of the base and the electrode main body disposed on the other surface of the base are opposed to each other with the base interposed therebetween is a detection portion, and the measurement instrument measures an amount of strain due to deformation by measuring changes in capacitance in the detection portion.
