Impedance measurement of piezoelectric devices is a prerequisite for the correct use of devices. For piezoelectric devices, the main parameters can be obtained through an impedance analyzer, including resonance frequency Fs, anti resonance frequency Fp, half power points F1 and F2, maximum admittance Gmax, static capacitance C0, dynamic reactance R1, dynamic capacitance C1, dynamic inductance L1, free capacitance CT, free dielectric constant, mechanical quality factor Qm, electromechanical coupling coefficient Keff, Kp, K31, K33, stb, And can draw five characteristic curves of piezoelectric devices (admittance characteristic diagram, impedance characteristic diagram, admittance polar coordinate diagram, impedance polar coordinate diagram, logarithmic coordinate diagram).
