Summary: Musculoskeletal conditions are becoming more prevalent and causing disability. Functional biomaterials, particularly piezoelectric materials, are receiving considerable interest in musculoskeletal tissue engineering. These materials can produce electrical signals in response to mechanical stimuli, making them highly relevant for regeneration processes. Compared to traditional electrotherapy, piezoelectric materials eliminate the need for external power sources and offer advantages for musculoskeletal tissue remodeling. This review focuses on the progress of lead-free piezoelectric materials in musculoskeletal tissue engineering, providing an interdisciplinary overview and clinical outlook.

Summary: In this study, excellent ferroelectric, piezoelectric, and dielectric properties were achieved in a lead-free piezoelectric ceramic system by coexistence of orthorhombic-tetragonal phase boundary and increased grain size. The addition of Li+ ions facilitated the increase in grain size and the shift of phase transitions, leading to desirable electrical properties and moderate Curie temperature. The sample with x = 0.03 exhibited large average grain size, coexistence of orthorhombic-tetragonal phases, and excellent physical properties. These favorable physical properties were attributed to the coexistence of phase transitions, large grain size, and hybridization between Bi 6p and O 2p.

Summary: This study demonstrates the design and application of a multifunctional piezoelectric composite nanofiber membrane. By adding ionic liquids and ferric chloride hexahydrate (FeCl3 center dot 6H(2)O) to polyacrylonitrile (PAN), the properties of the composite nanofibers, including mechanical, piezoelectric, dielectric, and ferroelectric properties, were improved. The results show that the composite nanofibers have great potential in energy storage devices and flexible piezoelectric sensors.

Summary: The study demonstrates a scaling effect in BaTiO3 and Ba0.83Sr0.17TiO3 ceramics with sub-millimeter thickness, showing reduced dielectric constant, increased coercive field, and decreased piezoelectric response. This effect is possibly due to surface layers with a stabilized ferroelectric phase and higher coercive field.

Summary: This work investigates the properties of PVASrTiO3 nanocomposite films by varying the concentration of SrTiO3 nanoparticles. The study reveals that the piezoelectric coefficient, dielectric constant, elastic modulus, and hardness strongly depend on nanoparticle concentration due to the formation of an interface layer between PVA matrix and SrTiO3. The apparent piezoelectric coefficient is proposed to be related to the converse flexoelectric effect and Maxwell stress induced by an electric field. The fine-tuning of the interface layer with functionalized nanoparticles results in a high apparent piezoelectric coefficient.

Summary: The structural evolution and electrical properties of 0.67Bi(1.03)FeO3-0.33BaTi(1-x)Zr(x)O(3) piezoelectric ceramics were studied, showing enhanced piezoelectric and ferroelectric responses near the morphotropic phase boundary. The dynamic piezoelectric coefficient gradually increased with temperature, while a large electrostrictive coefficient was obtained in a specific temperature range. The relationship between crystalline structure and functional properties suggests potential for future research into lead-free piezoelectric ceramics.

Summary: The study explores the development of next-generation electromechanical devices using ternary relaxor-PbTiO3 based ferroelectric crystals. Researchers have designed a monoclinic heterophase in a single crystal with optimized composition, which exhibits ultrahigh piezoelectric coefficient. Through high-resolution spectroscopic-microscopic technique, they observed two different heterophase mixtures responsible for different functionalities and correlated them with the ferroelectric-dominated and relaxor-ferroelectric-dominated nanodomain structure.
