FIELD: radio electronics. SUBSTANCE: unidimensional linear modes excited in rectangular piezoceramic element by placing it at variable-frequency voltage, rate of its mechanical resonance, components of elastic pliability, geometric dimensions, and active component of conductivity in resonant region are measured, and area under active component of conductivity is determined. These values are used as basis for computing piezoelectric moduli. Accuracy of piezoelectric modulus determination is consistent with frequency measurement error. EFFECT: improved accuracy of piezoelectric modulus determination.
