This paper reports on an indirect measurement of energy density of PZT-PNN ceramics utilizing mechanical stress. The method use Olsen like cycle and allows for a large amount of electro-mechanical energy conversion. A maximum energy density was achieved under 0-100 MPa and 1-15 kV/cm of applied mechanical stress and electric field, respectively. The obtained result is substantially higher than the results reported in previous studies in many piezoelectric materials utilizing direct piezoelectric effect.
