Bismuth ferrite‐barium titanate (BF‐BT)‐based ferroelectrics have received widespread attention due to its adjustable structure features and multifunctional characteristics. Property optimization (ferroelectricity, piezoelectricity, electrostrain, electrostriction) for different application scenarios can be realized by increasing BT content gradually, while it is still difficult to integrate multiple performance advantages in the same component. To solve the problem and achieve the simultaneous enhancement of property parameters, defect engineering was adopted in this work to balance domain configuration and relaxor state via selective oxides modification strategy. Compared with the nanodomain engineered relaxor ferroelectrics with improved electrostrain and degraded ferroelectricity, the defect‐mediated ceramics doped with MnO2 present both enhanced electrostrain and ferroelectricity. Multiscale structure analysis (crystal structure, defect structure, and domain structure) and property characterization (ferroelectricity, strain property, and leakage current density) suggested that the defect dipoles induced by Mn substitution can effectively refine domain size and maintain ferroelectric state at room temperature, and the easier domain switching caused by weak‐correlated polar dipoles greatly improves both the strain and ferroelectricity. Especially, the defect dipoles‐mediated nanodomain and property enhancement can be only observed in BFO‐Mn ceramics, and infeasible for other oxides (e.g., CuO and CeO2). We believe that this work can provide some guidance to modify electrical properties in BF‐BT‐based ferroelectrics.

A multifunctional fiber‐reinforced composite with passive self‐sensing, energy‐harvesting, and damage detection capabilities is presented. Here, barium titanate piezoelectric microparticles are deposited on basalt fibers by a scalable, low‐cost, environmentally friendly continuous feed‐through process. The resulting composite derives a superior interlaminar shear strength from the microparticle‐modified fiber–matrix interfaces. The composite also demonstrates passive self‐sensing capabilities that produce electrical signals proportional to various dynamic loading events. Vibration and strain‐controlled experiments are performed on composite beams to quantify the sensitivity and power output as a function of input acceleration and strain. Furthermore, these composite‐generated electrical signals are used to identify in situ damage initiation for structural health monitoring to inform composite damage prior to structural failure. In brief, this truly multifunctional composite simultaneously displays a sensitivity of 0.5–2.6 mV g−1 at a resolution of 0.045–0.20g (g = gravitational acceleration), energy harvesting in the range of nW cc−1, and prediction of early damage by exhibiting 0.017–1.17 mV peaks in voltage–time history profiles while assuring ≈20% improved interlaminar shear strength.

In conjunction with ultrahigh d 33 and Q m , the electrical fatigue behavior of high-power piezoelectric ceramics is highly relevant for practical applications. In this study, a comparative study of fatigue behavior between randomly oriented and ⟨001⟩ textured ceramics is investigated. It is found that ⟨001⟩ textured ceramics exhibit better fatigue resistance behavior in comparison with the random counterpart. The superior fatigue resistance of textured ceramics originates from its smaller domain size with high domain wall density, favorable domain wall switching, and internal stress relaxation during the electric field cycling process. Both mechanical damage and domain wall pinning mechanisms are found to play an important role in influencing the fatigue behavior of high-power textured ceramics. Detailed microstructural analysis along with electrical fatigue measurement under bipolar and unipolar modes is conducted to confirm the mechanisms controlling the degradation as a function of varying fields and temperatures. High-resolution electron microscopy results demonstrate that BaTiO 3 (BT) templates present within the textured ceramics do not induce mechanical damage during electric field cycling.
