This paper present generating characteristics of a hump shaped piezoelectric energy harvester. The harvester consists of a crooked elastic body plate and two ceramics which are attached on both inclined planes of the elastic body plates. This structure has a merit to lessen the stress of the ceramic because it can protect from direct pressure to the(More)
In this study, simple ultrasonic motor of plate type stator was proposed. Stator of the proposed ultrasonic motor was composed of an elastic plate and ceramics. The elastic plate has one tip in the middle. The two ceramics were attached on the side surfaces of the elastic plate. The both polarization directions were directed to the upward outside(More)
