Abstract
On this paper, unimorph type piezoelectric vibrator made by attaching ceramic plates on rectangular elastic body, to find the basic characteristic of the actuators. In experiment, elastic body's displacement and resonance frequency were measured according to changes of ceramic's length and elastic body's length. Also, temperature changes were observed according to time. The displacement and resonance frequency were increased when the ceramic's length were increased. When elastic body's length was increased, the displacement was increased. Also, the temperature was increased according to time, but at some time it was saturated and the temperature was not increased any more.
