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.
