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.

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.

Abstract: Provided are a power generation method and a power generating element capable of obtaining an electromotive force by utilizing humidity variation in an environment and having excellent operation stability. An aqueous solution of an ionic compound having deliquescence is separated by an ion permeable membrane, electrodes are inserted into the aqueous solution on both sides of the ion permeable membrane, one is blocked from outside air and sealed, and the other is connected to the outside air, and a difference in ion concentration derived from the ionic compound in the aqueous solution is generated across the ion permeable membrane due to a change in humidity in the outside air to generate an electromotive force between the electrodes.

Abstract: A stretchable raised electrode having a stretch property that can be used as a biological electrode for collecting biological signals while being pressed against a body is provided, and a method of manufacturing the stretchable raised electrode is provided. This raised electrode is a raised electrode formed by raising a surface of a sheet material having the stretch property. This raised electrode includes: a resin layer configured to be stretchable to follow the surface of the sheet material; and a plurality of conductive fibers each having an inserted portion, one end of which is inserted into the resin layer. The conductive fibers that are adjacent to one another are electrically in contact with one another at non-inserted portions into the resin layer, and the conductive fibers are formed in the resin layer so as to have such a density as causing an in-plane isotropic electric conductivity of an electrode region of the sheet material in which the conductive fibers are formed. This raised electrode can be obtained by an electrostatic spraying method.
