Abstract:
A measuring element for measuring dynamic pressure, temperature and/or static pressure includes a body made of a piezoelectric material and having opposing side surfaces carrying electrodes. The piezoelectric material of the body is selected in such a manner that a thrust coefficient of the piezoelectric e-tensor is not equal to zero, with the result that the inverse piezoelectric effect can be used, and a transverse coefficient of the piezoelectric d-tensor is not equal to zero and/or a longitudinal coefficient of the piezoelectric d-tensor is not equal to zero, with the result that the transverse piezoelectric effect can be used in the transverse direction and/or the longitudinal piezoelectric effect can be used in the longitudinal direction in a simultaneous manner with the inverse piezoelectric effect.
