Abstract Since industry‐standard piezoelectric materials, such as lead zirconium titanate ceramics, contain toxic lead, a rapid surge in research on lead‐free materials is occurring due to concerns over environmental safety and human health. A ternary (Na 0.5 Bi )TiO 3 ‐BaTiO ‐(K Na )NbO single crystal with large field induced strain of ≈0.9% giant coefficient d 33 840 pC N −1 at room temperature reported. It revealed that the electric‐field‐induced phase transition boundary between...
Abstract Tooth whitening has recently become one of the most popular aesthetic dentistry procedures. Beyond classic hydrogen peroxide-based agents, photo-catalysts and piezo-catalysts have been demonstrated for non-destructive on-demand tooth whitening. However, their usage challenged due to relatively limited physical stimuli light irradiation ultrasonic mechanical vibration. To address this challenge, we report here a convenient strategy based on pyro-catalysis effect, realized via...
Abstract With the rapid development of self‐powered electronics such as wearables, implantable devices, and sensor networks, there is an increasing demand for power sources that have a high density long lifespan to keep entire system operational. Flexible piezoelectric materials with capability mechanical‐to‐electrical energy conversion attracted significant interest because their immense potential harvesting human biomechanical energy. Herein, 3 mol.% yttrium stabilized zirconia ribbon...
High piezoelectric properties and low strain hysteresis (<i>H</i>) are both equally necessary for practical applications in precisely controlled devices systems. Unlike most of previous reports, where enhanced performance is typically accompanied by large lead-/lead-free-based ceramics, this work, we report a reconstructed relaxor ferroelectric composition 0.68Pb(Mg<sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub>–0.32PbTiO<sub>3</sub> (0.68PMN–0.32PT) ceramics through the introduction...
Tuning the ferroelectric domain structure by a combination of elastic and electrostatic engineering provides an effective route for enhanced piezoelectricity. However, epitaxial thin films, clamping effect imposed substrate does not allow aftergrowth tuning also limits electromechanical response. In contrast, freestanding membranes, which are free constraints, enable subtle balance between energies, giving new platforms tunable functionalities. Here, highly piezoelectricity is demonstrated...

It is observed that composition = 0.07 shows enhanced around ambient temperature due to ferroelectric–antiferroelectric phase transition, with p 6.83 × 10 −4 C m −2 K −1 figures merit F i 5.04...
The puzzle of resistivity irreversibility triggered by thermal cycling in perovskite charge ordering manganites has yet to be unraveled, largely due the absence a coherent explanation. application...
To meet the needs of future multilayer ceramic capacitors (MLCCs), thinner dielectric layers are necessary. achieve this goal, grain size and uniformity particles must be effectively controlled.
