Abstract
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 dprovided 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.
