Measurement System for Determining Piezoelectric Charge Coefficient

Abstract

The paper focuses on a system of direct measurement of piezoelectric charge coefficient. The created system is based on quasistatic method when harmonic force signal is applied to the examined piezoelectric material. A program in the programming environment LabVIEW was created for control, measurement, and processing. Thanks to the universality of this system from the perspective of hardware, this system offers higher levels of modularity than d33 meters available on the market.
