FLEXIBLE CONDUCTIVE MEMBER AND TRANSDUCER USING SAME

Title:

FLEXIBLE CONDUCTIVE MEMBER AND TRANSDUCER USING SAME

Document Type and Number:

WIPO Patent Application WO/2014/080470

Kind Code:

A1

Abstract:

This flexible conductive member is provided with: a base (31) having stretching properties; and a plurality of conductive layers (32, 33) that are laminated or arranged in parallel on the surface of the base (31). The conductive layers (32, 33) are: a first conductive layer (33) which is formed of a highly conductive material that contains an elastomer and a conductive material and has a volume resistivity of 5 × 10-2 Ω·cm or less at zero elongation; and a second conductive layer (32) which is formed of a highly stretchable conductive material that contains an elastomer and a conductive material and has a volume resistivity at zero elongation larger than the volume resistivity of the highly conductive material at zero elongation, while having a volume resistivity change of 10 times or less between the volume resistivity at 50% elongation and the volume resistivity at zero elongation.
