AbstractA 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. © 2010 The Electrochemical Society.
