“…For instance, the resonance spectrum inversion method converges more accurately as it has more resonance modes and does not easily converge to local solutions. However, introducing relatively more modes brings greater difficulties to modal identification 11 . The impedance spectrum‐based inversion method is another effective approach, benefiting from the high sensitivity of the impedance spectrum to the full matrix parameters and the simplicity of the testing conditions.…”

The full matrix parameters of a piezoelectric material are crucial for designing and evaluating piezoelectric devices. However, due to their inverse problematic nature, commonly used single‐sample characterization methods heavily depend on the accuracy of initial values and mode matching. In this paper, we propose a quasi‐31‐vibrator method to directly evaluate these parameters by designing the sample geometry and establishing the relationship equation between the parameters. This approach completely bypasses the need for characteristic spectrum simulation and mode identification processes. Subsequently, we tested the full matrix parameters of PZT‐5H ceramics and compared the simulated impedance spectra with the measured ones. The presence of well‐fitting spectra validates the feasibility of the method. This method will contribute to characterize the parameters of new piezoelectric materials and advance the intelligent implementation of measuring full matrix parameters.
