  • Patent number: 10184779
    Abstract: 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 ?m or more.

  • Patent number: 9658120
    Abstract: A capacitance-type sensor sheet used for measuring an amount of stretch deformation and strain and/or distribution of stretch deformation and strain may include a dielectric layer made of an elastomer, an obverse-side electrode layer laminated on the obverse surface of the dielectric layer, and a reverse-side electrode layer laminated on the reverse surface of the dielectric layer. The obverse-side electrode layer and the reverse-side electrode layer may each contain carbon nanotubes and the average thickness of the each of obverse-side electrode layer and the reverse-side electrode layer may be 0.1 ?m or more and 10 ?m or less. The obverse-side electrode layer and the reverse-side electrode layer may be formed by applying a coating solution containing carbon nanotubes. The obverse-side electrode layer and the reverse-side electrode layer may each include a plurality of band-shaped bodies.

  • Patent number: 7196224
    Abstract: The invention provides 1,3,5-tris(arylamino)benzenes represented by the general formula (I) wherein A is naphthyl, anthryl, phenanthryl, biphenylyl or terphenylyl group, and R is alkyl having 1–6 carbon atoms or cycloalkyl group having five or six carbon atoms. The 1,3,5-tris(arylamino)benzenes have oxidation potentials in the range of about 0.5–0.6V, excellent reversibility in oxidation-reduction process and high glass transition temperatures and in addition, they are capable of forming stable and durable amorphous film useful as high performance organic semiconductors at normal temperatures or higher with no aid of binder resins, that is, by themselves.
