“…With increasing temperature, the strain in the ceramics increased, with d 33 * increasing from 406 pm/V at room temperature to 759 pm/V at 125 °C (Figure f). Figure compares the field-induced strain ( d 33 *) of BF–BT–0.003Ce ceramics with those of other BF-based ceramics. ,,− The results indicate that BF–BT–0.003Ce ceramics exhibited a high T c of 418.2 °C and high attainable d 33 *, indicating their wide potential applications in high-temperature piezoelectric devices …”

“…However, difficulties in obtaining BiFeO 3 without secondary phases, its high coercive force field and conductivity combined with moderate piezoelectric activity make pure BiFeO 3 unsuitable for commercial use. This problem has been addressed by Ferrero et al 170 who have synthesized a potentially effective lead-free piezoelectric material called .67BiFeO 3 -.33BaTiO 3 (BF-BT) using a mechanochemical technique. XRD has no apparent secondary phase.…”

Mechanochemical synthesis is a technology formed in the 1950s. By applying mechanical energy, mechanochemical synthesis stimulates chemical reactions, causing structural and phase changes and enabling difficult or otherwise impossible reactions to occur. Mechanochemical reactions are relatively safe, clean and efficient. At present, the synthesis of oxide ceramic materials by mechanochemical methods has attracted widespread attention. In the production of oxide ceramic materials, the characteristics of ceramic powder have a certain influence on the molding, sintering, microstructure, and mechanical properties of subsequent ceramics. In this paper, the research progress of mechanical chemistry in the synthesis of nanostructures and composite oxide ceramic powders is reviewed. The effects of process parameters such as ball milling time, speed, atmosphere, grinding media, additives, and ball‐to‐powder ratio on reaction kinetics, phase formation, and powder properties are summarized. In addition, challenges and opportunities for ceramic powder synthesis are also discussed.

“…Internet of Things (IoT) and wearable electronics have attracted much attention in sensing technology; − however, unsustainable power supply for such sensors has become a serious challenge for their applications. − Traditional power-generation strategies are restricted by lifetime and frequent replacement. − Piezoelectric energy harvesters can convert ambient mechanical energy into electrical energy through a piezoelectric effect. − Piezoelectric ceramics and polymers are mainly used for piezoelectric energy harvesting. , The applications of piezoelectric ceramics, such as lead zirconate titanate (PZT) and barium titanate (BaTiO 3 ), in flexible wearable electronics are still restricted due to their high brittleness, poor flexibility, and low durability. − On the contrary, piezoelectric polymers, especially poly(vinylidene fluoride) (PVDF) and copolymers, are promising candidates for flexible electronic devices due to their excellent flexibility and thermal stability. , …”

With the rapid development of human−machine interactions and artificial intelligence, the demand for wearable electronic devices is increasing uncontrollably all over the world; however, an unsustainable power supply for such sensors continues to restrict their applications. In the present work, piezoelectric barium titanate (BaTiO 3 ) ceramic powder with excellent properties was prepared from milled precursors through a solid-state reaction. To fabricate a flexible device, the as-prepared BaTiO 3 powder was mixed with polydimethylsiloxane (PDMS) polymer. The BaTiO 3 /PDMS ink with excellent rheological properties was extruded smoothly by direct ink writing technology (DIW). BaTiO 3 particles were aligned due to the shear stress effect during the printing process. Subsequently, the asprinted composite was assembled into a sandwich-type device for effective energy harvesting. It was observed that the maximum output voltage and current of this device reached 68 V and 720 nA, respectively, for a BaTiO 3 content of 6 vol %. Therefore, the material extrusion-based three-dimensional (3D) printing technique can be used to prepare flexible piezoelectric composites for efficient energy harvesting.
