TOUCH SENSOR

摘要

A touch sensor that includes a pressure detection sensor and a position detection sensor. The pressure detection sensor and the position detection sensor are sequentially disposed from an operation surface side of the touch sensor. The position detection sensor includes a dielectric substrate, first position detecting electrodes on a first principal surface of the dielectric substrate, and second position detecting electrodes on a second principal surface of the dielectric substrate. The pressure detection sensor includes a piezoelectric film, a first piezoelectric detecting electrode on a first principal surface of the piezoelectric film, and a second piezoelectric detecting electrode on a second principal surface of the piezoelectric film. The first and second piezoelectric detecting electrodes are disposed so as to not overlap the first and second position detecting electrodes.

1. A touch sensor comprising:
a pressure detection sensor that includes a piezoelectric film and first and second piezoelectric detecting electrodes arranged on respective opposed sides of the piezoelectric film; and a position detection sensor that includes a dielectric substrate and first and second position detecting electrodes arranged on respective opposed sides of the dielectric substrate, wherein the pressure detection sensor and the position detection sensor are sequentially arranged from an operation surface side of the touch sensor, and the piezoelectric detecting electrodes and the position detecting electrodes are disposed so as to not overlap each other when viewed in a direction orthogonal to the operation surface.
