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. © 2010 The Electrochemical Society.
