Resum
An improvement of the description of the nonlinear behavior of PZT piezoelectric ceramics is proposed. The current obtained when applying a low frequency and high voltage harmonic signal is analyzed using a bridge, built ad hoc. The validity of no model is presupposed in the processing of data. Nonlinear behavior depends explicitly on the amplitude of the applied field. The nonlinear increment of the dielectric constant can be split into three fractions: the first one k f , is directly related t...
