Inequality of direct and converse piezoelectric coefficients
Ferroelectrics, 1981Abstract It is demonstrated theoretically and experimentally that the direct and converse piezoelectric coefficients. ∂P/∂σ and ∂e/∂E, are not equal as is generally believed. The correct relationship between these coefficients is derived, and it is shown that the experimentally measured quantities analogous to the piezoelectric coefficients are equal ...

Effective Piezoelectric Coefficient Calculation of Cymbal Piezocomposite
Ferroelectrics, 2002The "cymbal" metal-ceramic flextensional transducer has been developed for many actuator and sensor applications. In this device the ceramic driving element is sandwiched between two metallic endcaps with shallow cavities. The effective piezoelectric coefficient, d 33 eff , consists of the d 33 of the PZT disc and the contribution of the d 31 which is ...

Piezoelectric Coefficients New Opportunities to Improve Sensitivity
2018Piezoelectric coefficients hij characterise a link between an external mechanical strain applied to a sample and an electric field caused by the direct piezoelectric effect. At the converse piezoelectric effect, the piezoelectric coefficients hij characterise the link between a mechanical stress in the sample and electric displacement.
