CAPACITANCE-TYPE SENSOR SHEET, METHOD FOR MANUFACTURING CAPACITANCE-TYPE SENSOR SHEET, AND SENSOR

摘要

The present invention is a capacitance-type sensor sheet comprising: a dielectric layer made of an elastomer; an obverse-side electrode layer layered on the surface of the dielectric layer; and a reverse-side electrode layer layered on the reverse surface of the dielectric layer. The obverse-side electrode layer and the reverse-side electrode layer contain carbon nanotubes. The average thickness of the obverse-side electrode layer and the reverse-side electrode layer is 0.1 μm to 10 μm, respectively. The capacitance-type sensor sheet is used for measuring the amount of expansion and contraction deformation and strain and/or the distribution of expansion and contraction deformation and strain. The obverse-side electrode layer and the reverse-side electrode layer are preferably formed by coating a coating liquid containing carbon nanotubes. The average length of the carbon nanotubes is preferably 100 μm or more. The obverse-side electrode layer and the reverse-side electrode layer are preferably composed of a plurality of band-shaped bodies and disposed so that the obverse-side electrode layer and the reverse-side electrode layer intersect substantially at a right angle as viewed from the obverse-reverse direction.
