Traditional methods for characterizing piezoelectric materials typically involve analyzing their electromechanical response, focusing on coefficients such as the piezoelectric strain coefficient d33. In this study, an alternative approach is proposed to evaluate the piezoelectric response by examining the surface charge accumulated in the tested sample following a corona polarization process. Through the use of an electrostatic voltmeter, two influential factors affecting the piezoelectric response were investigated: the number of needles employed during the polarization and the presence of a grid interposed between the high-voltage needles and the specimen.

Abstract

Traditional methods for characterizing piezoelectric materials typically involve analyzing their electromechanical response, focusing on coefficients such as the piezoelectric strain coefficient d33. In this study, an alternative approach is proposed to evaluate the piezoelectric response by examining the surface charge accumulated in the tested sample following a corona polarization process. Through the use of an electrostatic voltmeter, two influential factors affecting the piezoelectric response were investigated: the number of needles employed during the polarization and the presence of a grid interposed between the high-voltage needles and the specimen.
