  • Patent number: 10386248
    Abstract: A stretchable electrically-conductive sheet according to the present invention includes an elastomer sheet 1 having an adhesive layer corresponding to a wiring region with a predetermined pattern formed on a front surface of the elastomer sheet, and also includes electrically-conductive fiber materials 2 each having a predetermined diameter and a predetermined length. When the elastomer sheet 1 is stretched or bended, the electrically-conductive fiber materials relatively move maintaining mutual electrical continuity so as to maintain the electrical continuity in the wiring region. Accordingly, it is possible to achieve a low-cost stretchable electrically-conductive circuit having excellent stretchability, bendability, and durability.

  • Publication number: 20190018511
    Abstract: [Problem] To provide a high-stretchability/contractibility stretchable contractible wiring sheet that can be produced easily at low costs, has high flexibility, high durability, and high conformity to external force, and undergoes small resistance value change along with stretching and contracting and a producing method and apparatus for the same, and a stretchable contractible touch sensor sheet. [Solution] A stretchable contractible wiring sheet of the present invention includes: a stretchable contractible first elastomer sheet 1a; a stretchable contractible second elastomer sheet 1b facing and bonded on the first elastomer sheet 1a; and a lead 2 interposed between the first elastomer sheet 1a and the second elastomer sheet 1b in a state of having a wavy shape periodically curving in-plane in facing surfaces of the first elastomer sheet 1a and the second elastomer sheet 1b and being biased in a direction to restore to a rod-like shape from the wavy shape during unloading.

  • Publication number: 20180033520
    Abstract: Conductor wires 2a and 2b are sandwiched between two elastomer sheets 1a and 1b whose adhesive layers face each other, and both adhere. When the elastomer sheets 1a and 1b are their natural lengths without being subjected to any tension, the conducting wires 2a and 2b are wound around into spiral shapes and contract. When tension is applied to the elastomer sheets 1a and 1b, the number of spiral turns of the conductor wires 2a and 2b decreases according to its extension and the conductor wires 2a and 2b extend. The conductor wires 2a and 2b are electrically connected to and fixed to a circuit element at both ends of the elastomer sheets 1a and 1b. As a result, it is possible to mass-produce, at low costs, highly stretchable wirings in which a change in resistance values due to extension thereof is small.
