Abstract

The piezoelectric shear response of 94.0(Ka_0.5, Na _0.5)NbO₃ (KNN) + 5.0LiNbO₃ (LN) + 0.5SrTiO ₃ (ST) + 0.5BiFeO₃ (BF) ceramics was investigated by Laser Doppler Vibrometry (LDV) and resonance-antiresonance method. From resonance-antiresonance method, the piezoelectric d₁₅ constant was obtained to be 273 pC/N. The shear strain obtained by LDV at the frequency of 150kHz showed strong nonlinearity. This suggested that the domain contribution to piezoelectric response in shear mode of KNN-LN-ST-BF ceramics existed at the operational frequency for the shear mode divices.
