摘要： A sensor device is provided which senses displacement using a piezoelectric film composed of a chiral polymer such as polylactic acid. The sensor device includes: a film (21) composed of, for example, PLLA; and electrodes for extracting an output voltage from the PLLA film (21), the electrodes being formed on main surfaces of the PLLA film (21) such that the electrodes face each other with at least a portion of the PLLA film (21) being interposed therebetween. The PLLA film (21) has a first side (24), which is fixed, and a second side (25), which is opposite to the first side (24) and serves as a movable portion (28). Each of the electrodes is configured to extract an output voltage resulting from an effect of piezoelectric constant d 14 provided by shear deformation caused by displacement of the movable portion (28) in a direction parallel to the main surfaces of the PLLA film (21), whereby an operation involving friction or the like can be sensed.

摘要： Disclosed is a piezoelectric sheet composed of a polylactic acid sheet and capable of exhibiting a high piezoelectricity in the thickness direction. A specific region (2) of a polylactic acid sheet (1) is heated by means of a microwave. To allow the polylactic acid sheet (1) to exhibit piezoelectricity in the thickness direction of the polylactic acid sheet (1), a high voltage is applied to the heated polylactic acid sheet (1) in the thickness direction of the polylactic acid sheet (1), and thereby the screw axes (3) of at least a part of the polylactic acid molecules are relatively aligned with the thickness direction. Then the polylactic acid sheet (1)is rapidly cooled, and thereby the polylactic acid molecules are immobilized. The same step is executed for other regions (4) of the polylactic acid sheet (1), and thereby piezoelectricity is imparted to a wide area of the polylactic acid sheet (1) in the thickness direction.

摘要： A dual TM-mode dielectric resonator apparatus comprises a dual TM-mode dielectric resonator consisting of two columnar TM-mode dielectric resonators (1) crossed inside a cavity (2); and a partition plate (3) of a window for electromagnetic field coupling between an external apparatus and the dielectric resonator. The partition (3) is disposed on the side surface of the cavity (2) opposing the external apparatus and constituted by forming a first shield conductor (30a) on a first main plane (S1) of a dielectric sheet (50) and a second shield conductor (30b) on a second main plane (S2). The first shield conductor (30a) includes parallel slits (32) formed in parallel with the longitudinal direction of one of the TM mode dielectric resonators, while the second shield conductor (30b) includes slits (31) formed in a region substantially opposed to the first slits (32). Further, a plurality of such dual TM-mode dielectric resonator apparatus described above are combined to form a band-pass filter. Accordingly, the degree of electromagnetic field coupling can be adjusted easily and precisely by adjusting the width of the first slits (31).
