piezoceramic resonators

This paper is devoted to analysis of the electric loading conditions problem for piezoceramic resonators' forced vibrations. New simple experimental technique together with computing permits us to study many resonators' parameters: admittance, impedance, phase angles, power components, etc. for constant input voltage, constant sample voltage and constant sample current electric conditions based on experimental data for "as it is" regime.

This paper is devoted to analysis of the modern achievements in energy loss problem for piezoceramic resonators. New experimental technique together with computing permits us to plot many resonators' parameters: admittance, impedance, phase angles, and power components etc. The author's opinion why mechanical quality under resonance is different from that under anti-resonance is given. The reason lies in clamped capacity and electromechanical coupling factor's value.
