摘要： A touch panel capable of detecting a pen and a finger, capable of corresponding to multi-touch, capable of detecting pressing force, and capable of reducing the use amount of a transparent electrode as much as possible. The touch panel has a piezoelectric sheet of poly-L-lactic acid having a predetermined stretching axial direction, electrodes that are opposed to each other and formed on the piezoelectric sheet do not cover the entire surface of the piezoelectric sheet and are formed so that they are discretely distributed in plural positions. The piezoelectric sheet is brought into the condition that tension is imparted in directions not coincident with the stretching axial direction.

摘要： A touch panel having a piezoelectric sheet with a first region and a second region, and a surface protection film bonded to the second region of the piezoelectric sheet with a non-curable adhesive. The non-curable adhesive has a larger elasticity than a material that bonds the first region of the piezoelectric sheet to the surface protection film.

摘要： A piezoelectric device is provided with a sound source IC, an amplifier for amplifying a sound source from the sound source IC, a piezoelectric speaker for generating sound based on a drive signal from amplifier, an MPU for performing a predetermined control process on the drive signal, a memory for storing temperature dependency information about the piezoelectric constant (d14) and Young's modulus E of the piezoelectric speaker, and a temperature sensor for detecting an ambient temperature. MPU has correcting unit, compares a detected result of the temperature sensor with the temperature dependency information, and performs temperature correction on the drive signal serving as an acoustic signal based on a compared result. The piezoelectric speaker outputs the acoustic signal temperature-corrected by correcting unit. Thus, it becomes possible to realize various piezoelectric devices, such as a piezoelectric speaker system, capable of preventing various input information from fluctuating even when there is a change in usage environmental temperature.

摘要： A sensor device that includes a film composed of, for example, PLLA; and electrodes for extracting an output voltage from the PLLA film. The electrodes are located on main surfaces of the PLLA film such that the electrodes face each other with at least a portion of the PLLA film being interposed therebetween. The PLLA film has a first side which is fixed, and a second side which is opposite to the first side and is a movable portion. Each of the electrodes is configured to extract an output voltage resulting from an effect of piezoelectric constant d14 provided by shear deformation caused by displacement of the movable portion in a direction parallel to the main surfaces of the PLLA film, whereby an operation involving friction or the like can be sensed.
