A simple electric circuit for teaching one-dimensional characterization of piezoelectric plates

This work presents a method based on elementary concepts of electric network for characterization of piezoceramics. A simplified version of Mason’s equivalent circuit is obtained applying basic theorems of electricity. The methodology employed to simplify the circuit is mandatorily presented in the issues addressed in introductory courses of electric circuits. The experimental development can be performed in laboratories for the teaching activities without further specific equipment. Using this methodology stimulates students because it is performed on devices very employed in technological application. Furthermore, it facilitates the understanding of physical principles present in the study of piezoelectric elements.
