Abstract

A single ring-shape ceramic plate piezoelectric actuator operated in shear-bending mode was proposed for high-temperature operation. The actuator was formed from BiScO 3-PbTiO 3 ceramic and polarized in the radial direction. A large bending displacement at the center of the actuator was piezoelectrically generated under an applied voltage in the thickness direction due to axial-symmetric shear strain of the ring-shape configuration. The displacement obtained at 200 °C was about 20 μm, 11-14 times that of a normal piezoelectric plate of identical size.
