Abstract

A methodology is proposed to estimate the piezoelectric coefficients of bulk piezoelectric materials using simple capacitance measurements. The extracted values of d₃₃ and d₃₁ from the capacitance measurements were 506 pC/N and 247 pC/N, respectively. The d₃₃ value is in agreement with that obtained from the Berlincourt method, which gave a d₃₃ value of 500 pC/N. In addition, the d₃₁ value is in agreement with the value obtained from the optical method, which gave a d ₃₁ value of 223 pC/V. These results suggest that the proposed method is a viable way to quickly estimate piezoelectric coefficients of bulk unclamped samples.
