Abstract

Three different piezoelectric stacks (PI, NEC, and Marco stack) were characterized in this paper. Their mechanical and electrical properties were first evaluated including Young' modulus, piezoelectric constants, and effective permittivity under mechanical preloads up to 69 MPa (10 ksi) at 2 MV/m. Test result shows that the PI stack generated the highest strain output (2087 με) under a mechanical preload of 55 MPa (8 ksi) at 2 MV/m. As electric field and frequency increased, piezoelectric stack was heated. Heating is mainly caused by power dissipated due to dielectric loss. The power density of the piezoelectric stack was measured under different frequencies, electric fields, and mechanical loads based on a factorial experimental design. Test results indicate that operational frequency influenced the power density more significantly than other parameters.
