A Strain-Based Methodology for the Estimation of Piezoelectric Coefficients
Mahmoud Al Ahmad
Abstract:Characterizing piezoelectric coefficients d33 and d31 is crucial in diverse applications. Here, an extensive analysis of the correlation between d33 and d31 in piezoelectric materials, employing strain relationships is presented. Utilizing the fundamental principles of stress and volume conservation, in conjunction with a capacitance voltage profile, d33 is extracted in terms of measured capacitance and the applied bias. This methodology promises advancements in piezoelectric material understanding and enginee… Show more
