Abstract: An electricity accumulation device includes an electricity accumulation element, an outer jacket material configured to house the electricity accumulation element, and a deformation sensor disposed on an expansive surface of the outer jacket material. The deformation sensor includes a sensor membrane having a base material made of an elastomer or a resin and conductive fillers filling the base material, the sensor membrane being subjected to bending deformation along with expansion of the outer jacket material, and a pair of electrodes connected to the sensor membrane. A three-dimensional conductive path is formed in the sensor membrane through contact between the conductive fillers. An electric resistance is increased along with an increase in amount of deformation of the sensor membrane from a natural state. The electricity accumulation device senses expansion of the outer jacket material on the basis of variations in electric resistance along with bending deformation of the sensor membrane.

Abstract: A bending sensor includes a high resistance layer; a low resistance layer having a crack and a lower electrical resistance than the high resistance layer in a state where the crack is closed; an insulating layer between the high and low resistance layers; and a plurality of electrode portions connecting electrically in parallel the high resistance and low resistance layers. In an OFF state where a bend amount is small, the crack is unlikely to open and a combined resistance of electrical resistances of the high resistance layer and the low resistance layer is output as OFF resistance from the plurality of electrode portions. In an ON state where the bend amount is large, the crack is likely to open and at least the electrical resistance of the high resistance layer is output as ON resistance higher than the OFF resistance from the plurality of electrode portions.
