Abstract

Large-strain multilayer actuators (MLAs) were fabricated by tape-casting 0.91(Na_1/2 Bi_1/2)TiO₃–0.06BaTiO₃–0.03AgNbO₃(NBT-BT–3AN) lead-free incipient piezoceramics co-fired with Pt inner electrodes. Microstructures, dielectric properties, unipolar and bipolar strain, as well as fatigue properties of the MLAs were investigated. It was found that the actuator consisting of 15 ceramic layers with individual thicknesses of 114 μm could output a large unipolar strain of 0.3% and a dynamic displacement of 5 μm at 6 kV/mm at room temperature. It exhibited excellent cycling stability and provided a high strain of 0.23% after 10⁷ cycles at 6 kV/mm. Moreover, these MLAs still can deliver a strain of 0.20% at 125°C.
