The ban of lead in many electronic products and the expectation that, sooner or later, this ban will include the currently exempt piezoelectric ceramics based on Lead-Zirconate-Titanate has motivated many research groups to look for lead-free substitutes. After a short overview on different classes of lead-free piezoelectric ceramics with large strain, this review will focus on Bismuth-Sodium-Titanate and its solid solutions. These compounds exhibit extraordinarily high strain, due to a field induced phase transition, which makes them attractive for actuator applications. The structural features of these materials and the origin of the field-induced strain will be revised. Technologies for texturing, which increases the useable strain, will be introduced. Finally, the features that are relevant for the application of these materials in a multilayer design will be summarized.

“…In the same year, Nagata et al reported Li‐doped NBT‐based MLAs with Pt electrodes, 10 active layers with thickness of 125 μm per layer, and a maximum strain of 0.17% at 7 kV/mm. Reichmann et al prepared a NBT‐based piezoelectric MLAs with temperature‐stable strain of 0.19% at 7 kV/mm . Sapper et al fabricated a lead‐free piezoelectric MLA with BNT‐6BT‐3KNN, which achieved a strain of 0.15% at 6 kV/mm.…”

Large‐strain multilayer actuators (MLAs) were fabricated by tape‐casting 0.91(Na1/2 Bi1/2)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.

“…First viable contenders and products are now appearing at the marketplace. [3][4][5] However, the properties of most lead-free materials are still lower in comparison to PZT. [6][7][8] Thus, development of lead-free piezoelectric ceramics is of great interest.…”
