초록

On this paper, piezoelectric transducer was studied through direct piezoelectric effect. Circular unimorph type piezoelectric transducer is fabricated by attaching circular type PZT ceramic to circular plate of brass. The fabricated transducer was simulated and analyzed by using FEM program, ANSYS. Output characteristics were measured by applying diverse frequencies, including resonance frequency, of vibrator to transducer, and then the results were compared with ANSYS results. In addition, each characteristic was measured at two constraint conditions to obtain higher efficiency.
