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: Provided are a stretchable humidity-sensitive composite material for a humidity sensor that can be applied to clothing as wearable device, and the humidity sensor. The humidity-sensitive composite material is characterized by containing a deliquescent inorganic compound in closed pores inside a base material made of a porous silicone resin. The humidity sensor is characterized in that a bulk made of a humidity-sensitive composite material containing a deliquescent inorganic compound in closed pores inside a base material made of a porous silicone resin is sandwiched between a pair of counter electrodes made of a moisture-permeable material.

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: 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.
