Abstract:
Piezoelectric bar transducers are commonly used for generating low frequency flexural mode vibrations. The paper calculates the electromechanical properties including the effective electromechanical coupling coefficient of the stripe-electroded tangentially polarized bar transducer vibrating in flexure under the simply supported boundary condition. A numerical analysis is used to model the curved electric field lines. Calculations take into account the internal energies due to the contributions of the transverse and longitudinal piezoelectric effects and the modal strain distribution in the bar. Results are presented as functions of distance between the electrodes and thickness of elements and are compared with traditional bimorph designs employing either transverse or longitudinal polarization.
