Abstract: A touch sensor that includes a pressure detection sensor and a position detection sensor. The pressure detection sensor includes a piezoelectric film, a first piezoelectricity detecting electrode adjacent a first principal surface of the piezoelectric film, and a second piezoelectricity detecting electrode adjacent a second principal surface of the piezoelectric film. The position detection sensor includes a dielectric substrate, a plurality of first position detecting electrodes adjacent a first principal surface of the dielectric substrate, and a plurality of second position detecting electrodes adjacent a second principal surface of the dielectric substrate.

Abstract: A vibration device that includes a flat plate that has a first main surface and a second main surface; a vibrator that is configured to vibrate along a first direction parallel to the first main surface; a connecting member that connects the vibrator to the first main surface of the flat plate; a support member having a cavity or a recess in a portion thereof facing the vibrator; and a cushioning material connecting the first main surface of the flat plate to the support member, the cushioning material being disposed so as to not overlap with the vibrator in a plan view of the vibration device. A combined length of the vibrator and the connecting member in a second direction perpendicular to the first main surface of the flat plate is larger than a length of the cushioning material in the second direction.

Abstract: A piezoelectric sensor that includes a piezoelectric film, first and second adhesive layers, first and second plate electrodes and a glass plate. The piezoelectric film includes first and second principal surfaces. The first adhesive layer attaches the first plate electrode to the first principal surface. The second adhesive layer attaches the second plate electrode to the second principal surface. The second plate electrode is attached to the glass plate such that the second adhesive layer and the second plate electrode are interposed between the piezoelectric film and the glass plate. The glass plate is distorted by being pushed. The second adhesive layer is thicker than the first adhesive layer.

Abstract: An electronic device with pressing input function includes a substantially rectangular parallelepiped-shaped housing. A pressure sensor, a display panel, a protective member, and an arithmetic circuit module are disposed in the housing. In the display panel, a front polarizing plate is disposed on a front face of a liquid crystal panel. The pressure sensor includes piezoelectric films having birefringence, and electrodes formed on opposed faces of one of the piezoelectric films. The pressure sensor is disposed between the liquid crystal panel and the front polarizing plate. The piezoelectric films are arranged such that their uniaxial drawing directions are orthogonal to each other.
