“…17,18 This proves that the large strain of actuator at 200°C comes from the intrinsic properties of BS-PT:0.3wt%CuO piezoelectric layer in deed. Although extensive studies focused on the Pb-free piezoelectric ceramics and their multilayer actuators recently and some of them showed a strain as high as ≥0.4% at room temperature, [26][27][28][29][30][31] there is still a long way for them to be applied in industries mainly because the ceramic MPBs and piezoelectric properties are not stable enough with the ambient temperature changing or the ceramic sintering temperature (eg, above 930°C) is too high to use pure Ag electrodes. As a comparison, the BS-PT:0.3wt%CuO ceramic shows good temperature stability of MPBs, piezoelectric and mechanical properties at 20-200°C.…”

High‐temperature multilayer actuators based on Cu doping 0.367BiScO3–0.633PbTiO3 ceramic slices and Ag electrodes were prepared by low‐temperature co‐firing technology. The 0.3 wt% CuO addition has effectively reduced the sintering temperature of the ceramic from ~1080 to 930°C, thus the multilayer actuator were sintered at 930°C which is lower than the Ag melting point, that is, 961°C. The 4.3 mm thick multilayer actuator is composed of a series of ~44‐μm‐thick ceramic slices and ~2‐μm‐thick Ag electrodes. As a result, a ≥0.13% strain with nm‐scale preciseness can be produced in the actuator by 200 V driving voltage not only at room temperature but also at a high temperature up to 200°C. This actuator is essential for industrial machinery that requires nm‐scale position control at 20‐200°C.

Increasing concern has been focused on the search for ecofriendly dielectric ceramics to meet the extensive demands of pulsed capacitors. Due to the advantages of high-energy storage density, efficiency, and excellent temperature stability, optimization of energy storage performance in dielectric ceramics has been a goal in the past decades. This review summarizes the recently reported progress in energy storage properties of typical perovskite-type lead-free ceramics. The advantages and shortcomings in the various kinds of ceramics are discussed. Finally, future prospects are presented to provide some guidelines for the exploration of new materials.

Dielectric materials with ultrahigh permittivity are attracting attention due to the increasing demand for these types of materials for microelectronics and energy storage applications. In this work, we successfully synthesized Zn‐doped CdCu3Ti4O12 (CdCTO) ceramics with low dielectric loss and large permittivity via an ordinary mixed‐oxide technique. Remarkably, at a Zn doping level of 0.10, a CdCu2.9Zn0.1Ti4O12 ceramic exhibited both decreased dielectric loss tangent of ~0.058 and large dielectric permittivity > 4.0 × 104, as well as a good frequency stability over a wide frequency range from 40 Hz to 106 Hz. The high dielectric performance was attributed to the enhanced grain boundary resistance and internal barrier layer capacitor (IBLC) effect due to the fine and uniform grains that formed upon Zn doping. The findings reported in this work provide valuable insights into how to simultaneously realize a low dielectric loss and high permittivity in CdCTO and other related dielectric ceramics.
