Japanese Patent JP7060847
Kind Code:
B2
Abstract:
[Problem] To provide a stretchable capacitor that shows a 1:1 relationship between degree of stretching and capacitance and has high sensitivity and no hysteresis, and to apply the same to a respiration sensor or sensing wear. [Solution] Provided is a capacitor having a layered structure in which at least a stretchable conductor layer, a stretchable dielectric layer, and a stretchable conductor layer are stacked in that order, wherein the stretchable capacitor is obtained by using: the stretchable conductor layers that are a composition containing metal particles and that is characterized in that the specific resistance when not stretched is 3 × 10−3 Ωcm or less and the specific resistance when 100% stretched is no greater than 100 times the specific resistance when not stretched; and a stretchable dielectric layer with little inorganic constituents, preferably with a Poisson ratio of at least 0.28. The obtained stretchable capacitor can be attached to a belt, shirt, or the like and is capable of sensing respiration on the basis of changes in a sleeveless garment. Moreover, if the stretchable capacitor is placed in an indirect location or the like of clothing, the motion of the wearer can be read.
