Mechanical, electrical and transducer properties of piezoelectrics are estimated using a newly proposed method. Transducer properties of piezoelectrics, i.e., power generation and energy conversion properties, are useful for application to power microelectromechanical system (MEMS) devices. Electrical and mechanical properties of piezoelectrics could be estimated from the viewpoint of application to electronic devices using a trial measuring apparatus. The electromechanical coupling constant is estimated in the case of pure and impurity doped lead zirconate titanate (PZT) using the same apparatus under short- and open-circuit conditions. The electromechanical coupling constant is calculated from the mechanical properties, i.e., two kinds of Young's modulus.
