Temperature dependence of the main piezoelectric parameters
Original language description
The thesis deals with the piezoelectric coefficients, the resonance frequency and especially the piezoelectric constants verification. The resonance and the anti-resonance frequencies as well as impedance and capacitance of samples are measured with several devices, for instance LCR-meter Agilent E4980A,. The paper opens with the theory of the piezoelectric phenomenon and the difference between direct and indirect piezoelectric phenomenon. Further, the paper describes various piezoelectric constants andtheir calculations. Subsequent part of the paper is dedicated to the temperature dependence of the main piezoelectric parameters of PZT ceramics. The materials coefficients are delineated as a function of temperature of the piezoelectric charge coefficients dij, relative permittivity ?r, electromechanical coupling factor kij and frequency constants Ni. An important number of piezoelectric constants were determined, but we are going to present only piezoelectric charge constant d33 and d
