Abstract
A capacitive sensor includes a sensor sheet having a central electrode layer and a measuring instrument. A first dielectric layer is laminated on the upper surface of the central electrode layer. A second dielectric layer is laminated on the lower surface of the central electrode layer. A first outer electrode layer is formed on the surface of the first dielectric layer. A second outer electrode layer is formed on the surface of the second dielectric layer. The central electrode layer and the first outer electrode layer face each other at a first detection portion. The central electrode layer and the second outer electrode layer face each other at a second detection portion. Capacitances of the detection portions change with deformation. The state of deformation of the sensor sheet is measured on the basis of the total capacitance by adding the capacitances of the first detection portion and the second detection portion.
