The bipolar and unipolar fatigue behavior of the lead-free piezo- and ferroelectric 0.94Bi(1/2)Na(1/2)TiO(3)-0.06BaTiO(3) (94BNT-6BT) was investigated. To obtain a complete profile of the fatigue behavior, both large-signal (polarization, strain) and small-signal (d(33), epsilon(33)) properties were measured at room temperature. The results indicate that the material suffers a significant degradation in both large- and small-signal properties after cycling, with most of the fatigue occurring in the first 104 cycles of the fatigue test.
