The (0.98- x )(0.6Pb(Mg 1/3 Nb 1/3 )O 3 -0.4PbTiO 3 )- x Pb(Yb 1/3 Nb 1/3 )O 3 -0.02Pb(Er 1/2 Nb 1/2 )O 3 ((0.98- x )(PMN-PT)- x PYN:Er 3+ ) ceramics were prepared through a solid-state reaction method. The phase structure, piezoelectric response, ferroelectric performance and upconversion emission of the ceramics were systematically investigated. The phase structure, the electrical and optical properties are strongly related to the content of PYN. The optimized piezoelectric response and upconversion emissions of the ceramics were achieved near x = 0.12, which locates in the morphotropic phase boundary (MPB) composition. Furthermore, the temperature sensing behaviors of the resultant compounds based on the thermally coupled levels of 2 H 11/2 and 4 S 3/2 of Er 3+ ions in the temperature range of 133–573 K were studied by utilizing the fluorescence intensity ratio technique. Additionally, the thermal effect, which is induced by the laser pump power, of the studied ceramics is also investigated and the produced temperature is enhanced from 268 to 348 K with the pump power rising from 109 to 607 mW.

Relaxor-based ternary Pb( In 1 / 2 Nb 1 / 2 )O 3 –Pb( Mg 1 / 3 Nb 2 / 3 )O 3 –PbTiO 3 (PIN–PMN–PT) single crystals and ceramics are promising candidates for high-performance electromechanical conversion devices. It is known that the domain structure and dielectric diffusion–relaxation characteristics are crucial to the excellent performances of relaxor ferroelectrics. In this work, we prepared the PIN–PMN–PT ceramics with various PIN/PMN proportions and systematically investigated their domain structure and dielectric diffusion–relaxation properties. The effect of PIN/PMN proportion on the domain size and dielectric diffusion–relaxation characteristics was also studied. The investigations showed that PIN–PMN–PT ceramics presented multi-type domain patterns comprising irregular island domains and regular lamellar domains. Moreover, the dependent relations of PIN/PMN proportions on the dielectric diffusion and domain size indicated that the PIN composition has a stronger lattice distortion than PMN composition; increasing the PIN proportion can enhance the dielectric diffusion and decrease the domain size. Our results could deepen the understanding of structure–property relationships of multicomponent relaxor ferroelectrics and guide the design and exploration of new high-performance ferroelectric materials.

Visual monitoring of human motion signals using piezoelectric sensors offers critical insights for personalized exercise training and health rehabilitation. However, conventional piezoelectric sensors often face a fundamental trade-off between mechanical strength and electrical output, limiting their effectiveness in these applications. Here, we propose a hierarchically gradient structure based on lead magnesium niobate-lead titanate (PMN-PT) and polyvinylidene fluoride (PVDF) piezoelectric nanocomposite to alleviate this dilemma. This design leverages the exceptional flexibility of PVDF and the superior electrical properties of PMN-PT to enhance piezoelectric output and mechanical strength simultaneously. Both experimental tests and finite element analysis simulations reveal that the proposed gradient architecture facilitates stress redistribution and enhances crystallinity of the composite, synergistically improving its electromechanical coupling performance. Consequently, the fabricated sensor exhibits a 2.36-fold higher sensitivity (83.1 mV/N) compared to pure PVDF, along with nearly doubled flexibility (27 % elongation at break). Experimental validation confirms that the gradient-structured sensor can conformally adhere to various locations for motion monitoring. This system offers a reliable approach for dynamic biomechanical capture, enabling quantitative assessment and personalized guidance during exercise training and rehabilitation programs.

Grain-oriented growth enabled by aligned template seeds stands as the cornerstone for developing advanced textured ferroelectric ceramics. In this work, the templated-grain-growth behavior and corresponding electric properties of [001]-textured PIN-PMN-PT ternary ferroelectric solutions with high PIN content were investigated systematically. Pronounced grain-oriented-growth was achieved as PIN content within 45 mol%, while texturing development was significantly constrained in ceramics with a PIN content exceeding 50 mol%. The failure of highly-texturing could be attributed to the excessive lattice mismatch between BaTiO 3 templates and PIN-PMN-PT matrix. Concurrently, higher PIN content contributed to enhanced piezoelectric response in PIN-PMN-PT textured ceramics under high electric field loading. The highly [001]-textured PIN-PMN-PT ceramics with F 001 > 96% revealed remarkably high strain S m > 0.40% accompanied by ultra-low strain hysteresis H s ∼ 6.0%.

Mechanical energy can be directly transformed into chemical energy by piezoelectric materials, namely, piezocatalysis, which is a potential tactic for renewable clean energy collection and environmental purification. The piezocatalytic efficiency strongly relies on the piezoelectric property and free charge concentration of piezocatalysts. Here, four samarium-doped (1 – x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 nanostructures were designed to investigate the correlation between the piezoelectric property and piezocatalytic performance. The diverse dye degradation efficiencies confirmed the high piezoelectric coefficient toward high catalytic activity. The degradation efficiency for acid orange 7 (AO7) was 100% within 20 min, while those for methyl orange (MO), methylene blue, and rhodamine B dyes were 97, 78, and 72%, respectively, within 40 min under ultrasonic vibration only. Furthermore, high catalytic efficiency of 96% was still maintained for AO7 degradation after 10 consecutive degradation cycles for samarium-doped 0.70Pb(Mg1/3Nb2/3)O3-0.30PbTiO3 due to its high piezoelectric coefficient. The investigation of the catalytic mechanism demonstrated that hole and superoxide radicals were the primary active species toward AO7 degradation, whereas hydroxyl and hole radicals were for MO degradation. This work not only demonstrates the highly efficient catalytic activity of samarium-doped (1 – x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 nanostructures but also gives a deep comprehension of the correlation between the piezoelectric property and catalytic performance of piezocatalysts.

Transparent ferroelectric materials have garnered extensive attention from researchers due to their superior optical and electrical properties, enabling applications in medical photoacoustic imaging, transparent piezoelectric transducers, and other fields. As a new generation of transparent piezoelectric ceramics, PIN-PMN-PT shows broader application potential. However, there is a trade-off among the transmittance, piezoelectric performance, and Curie temperature of PIN-PMN-PT ceramics, making it challenging to prepare materials that simultaneously feature high transmittance, strong piezoelectricity, and a high Curie temperature. Researchers have long recognized that compositional design within the morphotropic phase boundary (MPB) can optimize material properties, and rare-earth doping strategies introducing local heterogeneity further enhance performance. It should be noted that rare-earth doping inevitably causes slight shifts in the MPB, yet current studies on ternary PIN-PMN-PT ceramics are often confined to the MPB region of undoped samples. Therefore, exploring the influence of rare-earth doping on the MPB is of great significance. In this work, 1 mol% Sm-15PIN-PMN- x PT ( x = 31, 33, 35, 37, 39) transparent ferroelectric ceramics were prepared via a two-step sintering method. It was found that when the phase structure is a coexisting rhombohedral-tetragonal structure with the tetragonal phase slightly exceeding the rhombohedral phase, a mixed-domain morphology of ferroelectric domains is induced, endowing the sample with optimal comprehensive performance. Specifically, 1 mol% Sm-15PIN-PMN-35PT ceramics exhibit a room-temperature d 33 of 760 pC/N, an optical transmittance T of 62 % @ 2000 nm, and a Curie temperature of 187.4 °C. Notably, the d 33 reaches 1100 pC/N at 96 °C, the highest value reported for PIN-PMN-PT piezoelectric ceramics to date. This study provides valuable experience and insights for the design and preparation of transparent ferroelectric ceramics with excellent comprehensive properties.

Dual-mode imaging combining photoacoustic and ultrasound modalities holds great promise for comprehensive tissue characterization. In traditional dual-mode imaging systems, however, the opaque ultrasound transducers are integrated in complex optical and ultrasound paths, leading to compromises in imaging efficiency and sensitivity. To address these challenges, we design and produce highly transparent Pb(Mg,Nb)O 3 PbTiO 3 ceramics with exceptional transparency of 68%, alongside a remarkable ultrahigh piezoelectric d 33 of 1500 pC/N. Leveraging this material, we fabricate a high-sensitivity transparent piezoelectric ultrasound transducer (TPUT) with a center frequency of 16 MHz and a bandwidth of 30%, which seamlessly integrating ultrasound and photoacoustic capabilities into one system to achieve simultaneous photoacoustic/ultrasound dual-mode imaging, showcasing a remarkable sensitivity for deep-tissue detection ( e.g. , 7.5 mm thick chicken breast meat). Additionally, in vivo photoacoustic imaging of subcutaneous microvasculature in a mouse ear was successfully achieved via 28 MHz TPUT. Our innovation not only advances imaging performance but also offers a cost-effective solution, paving the way for transformative biomedical imaging applications.

Piezoelectric sensors have attracted great attention owing to their capability of directly converting mechanical stimuli into electrical signals. The properties of piezoelectric materials and their manufacturing techniques significantly impact the performance of a piezoelectric sensor. Herein, a piezoelectric composite is developed by integrating PMN–PT ceramic particles with superior piezoelectric properties into a flexible PDMS polymer matrix, and piezoelectric sensors with patterned structures are successfully fabricated via direct ink writing (DIW) 3D printing. It was demonstrated that the PMN–PT/PDMS piezoelectric sensor achieved a maximum sensitivity of 914 mV·N1–, which is approximately twice the values obtained from previous related studies. Moreover, the sensor is sensitive to structural variations, making it feasible to tune the piezoelectric output. This work demonstrates that 3D-printed piezoelectric sensors with rational structural design enable a more sensitive perception of mechanical stimuli, providing a viable strategy for intelligent security identification and human motion detection.

In this study, a relaxor ferroelectric ceramic, 0.67Pb(Mg1/3Nb2/3)O3–0.33PbTiO3 (PMN–PT), was synthesized by a molten-salt growth method with lower remnant polarization and slimmer hysteresis loops than traditional ferroelectric ceramics. The PMN–PT particles remained homogeneously dispersed in the composite and adhered tightly to a poly(vinylidene fluoride-co-hexafluoropropylene) (P(VDF-HFP)) matrix due to the modification of the particles with dopamine. The composites had a maximum dielectric constant of 65.1 and a low dielectric loss of less than 0.037 at 1 kHz. Due to the low remnant polarization of the relaxor ferroelectric ceramic of PMN–PT, the energy density of the composites significantly increased. The discharged energy density of the sample with 50 vol% PMN–PT was 4 times that of P(VDF-HFP) at 80 kV mm−1. It was demonstrated that the dopamine functionalized PMN–PT/P(VDF-HFP) composite was a potential dielectric material with potential future applications in energy storage.

Ternary piezoelectric ceramics Pb(In 1 ∕ 2 Nb 1 ∕ 2 )O 3 –Pb(Mg 1 ∕ 3 Nb 2 ∕ 3 )O 3 –PbTiO 3 (PIN–PMN–PT) exhibit excellent temperature stability and hold great potential for high-frequency and high-power applications. However, its piezoelectric performance is much lower than that of the famous binary Pb(Mg 1 ∕ 3 Nb 2 ∕ 3 )O 3 –PbTiO 3 (PMN–PT) system. In this work, high-performance 15PIN–50PMN–35PT piezoceramics with piezoelectric coefficient d 3 3 of 700 pC/N, electromechanical coupling coefficient k p of 66% and high Curie temperature T C of 1 9 9 ∘ C were fabricated. Effect of Samarium (Sm) doping content on the ferroelectric, dielectric, electromechanical and piezoelectric properties and structures of 15PIN–50PMN–35PT piezoelectric ceramics were investigated, and results reveal that increasing the amount of Sm doping leads to a significant decrease of d 3 3 , k p , T C and other properties. This phenomenon is different from the previously reported results in Sm-doped binary PMN–PT ceramics. The room temperature and variable temperature phase structure and room temperature microstructure were studied to explain this phenomenon.

To address the demand for high-precision piezoelectric devices featuring high piezoelectric performance and excellent temperature stability, x Ce-PMN-35PT piezoelectric ceramics were synthesized via cerium doping. Ce ions preferentially occupy the A-site substituting for Pb 2 + , as evidenced by XRD peak shifts and Raman spectral evolution. Combined lattice variation and ionic radius data suggest a valence evolution from Ce 4+ towards Ce 3+ with increasing doping content. The results show that the ceramic with 2 mol% Ce doping exhibits superior comprehensive performance: the piezoelectric coefficient d 33 reaches 780 pC/N, the large-signal piezoelectric coefficient d 33 * is 1101 pm/V, and the unipolar electrostrain only degrades by 6.4% across the broad temperature range from 25 to 125 ℃. Through in situ XRD and Rietveld refinement, this study further elucidated the intrinsic correlation among phase structure, domain switching dynamics, and piezoelectric properties, thereby revealing the underlying mechanism by which cerium doping optimizes material performance. This work not only offers a promising material system for medium-temperature high-precision piezoelectric actuators but also presents an effective strategy for tailoring the properties of PMN-PT-based ceramics.

Electrostrictive materials have been actively studied for applications in precision machinery, laser communication, and biological microscopy due to their numerous advantages, including high resolution, negligible hysteresis, low heat dissipation, and fast response. Nevertheless, simultaneously achieving high strain and low hysteresis in electrostrictive materials presents a great challenge, impeding the development of high precision positioning devices. In this study, we designed a critical phase point where the relaxor state coexists with the rhombohedral and tetragonal phases, offering a favorable environment for the reversible transition from the ergodic relaxor state to an unstable long-range ordered ferroelectric state under an external electric field, enabling a high electrostrictive strain. To achieve this strategy, we introduced a strong relaxor component by incorporating a Nd dopant into Pb(Mg1/3Nb3/2)O3–PbTiO3 (PMN–PT) ceramics, thereby enhancing local structural heterogeneity. The resulting 4%Nd-doped 0.69PMN–0.31PT ceramic exhibits an excellent electrostrictive strain of 0.22% with a highly effective piezoelectric strain coefficient Smax/Emax = 730 pm V−1 at 30 kV cm−1, superior to those of previously reported electrostrictive ceramics and most piezoelectric ceramics. Moreover, the 4%Nd-doped 0.69PMN–0.31PT ceramic demonstrates favorable temperature stability, maintaining an electrostrictive strain of 0.15% at temperatures up to 80 °C. This work provides an effective way to obtain high-performance electrostrictive materials via synergistically enhancing local structural heterogeneity and designing a morphotropic relaxor phase boundary.
