The lead-free material based on BaTi0.9Zr0.1O3 solid solution (BZT) is shown to be one of the most promising for producing actuators. The study of multilayer BZT capacitors of 100 μm layer thickness was investigated in a wide temperature range and under strong electric field. In the temperature range between -15°C and 40°C, the capacitors showed good dielectric and electrostrictive parameters: high nonlinearity of dielectric constant, strain stability as low as 20%, and no electromechanical hysteresis. The observed properties can be explained by coexistence of ferroelectric and paraelectric phases in BZT around the room temperature.
