“…However, the (200) peak appears to be asymmetric, and was deconcoluted into (002) and (200) peaks. The merging of (002) and (200) peaks into unresolved (200) peak is well acknowledged as a sign of reduced tetragonality [21,22], which can be caused by the substitution of p-type acceptor into the BaTiO 3 lattice [23]. In this study, only Cu is an alien p-type dopant that can be doped into the BaTiO 3 lattice.…”

The use of piezoceramic materials for structural sensing and actuation is a fairly well developed practice that has found use in a wide variety of applications. However, just as advanced composites offer numerous benefits over traditional engineering materials for structural design, actuators that utilize the active properties of piezoelectric fibers can improve upon many of the limitations encountered when using monolithic piezoceramic devices. Several new piezoelectric fiber composites have been developed; however, almost all studies have implemented these devices such that they are surface‐bonded patches used for sensing or actuation. This paper will introduce a novel active piezoelectric structural fiber that can be laid up in a composite material to perform sensing and actuation, in addition to providing load bearing functionality. The sensing and actuation aspects of this multifunctional material will allow composites to be designed with numerous embedded functions, including structural health monitoring, power generation, vibration sensing and control, damping, and shape control through anisotropic actuation. This effort has developed a set of manufacturing techniques to fabricate the multifunctional fiber using a SiC fiber core and a BaTiO3 piezoelectric shell. The electromechanical coupling of the fiber is characterized using an atomic force microscope for various aspect ratios and is compared to predictions made using finite element modeling in ABAQUS. The results show good agreement between the finite element analysis model and indicate that the fibers could have coupling values as high as 68% of the active constituent used.

“…Therefore, in order to obtain BaTiO 3 nano-powders with high tetragonality, improved hydrothermal syntheses such as solvothermal synthesis and microwave-hydrothermal synthesis are extensively attempted. [14][15][16][17][18] In this study, we attempted to synthesize nano-sized BaTiO 3 powders with narrower size distribution and higher tetragonality by the hydrothermal process with rotary manipulation. This technique is a novel hydrothermal process that uses neither alcohol as a solvent nor microwave.…”

Nano-sized BaTiO 3 powders with narrow size distribution and high tetragonality were attempted to be synthesized by the rotary-hydrothermal process in a water system as a novel technique, using a mixture of anatase-type TiO 2 and Ba(OH) 2 as starting material. The rotary-hydrothermal syntheses were performed under conditions with a rotary-speed of 20 revolutions per minute at 423-523 K for 3-96 h. Highly-and monodispersed BaTiO 3 powders mainly composed of coarse-faceted particles with the tetragonal phase were successfully synthesized by controlling the conditions for rotary-hydrothermal treatments. TEM and TG results revealed that these coarse-faceted BaTiO 3 particles contained very few structural defects such as hydroxyl content. Thus, the rotary-hydrothermal process was a useful method to synthesize very high-quality BaTiO 3 particles, and the further control of various conditions of the rotaryhydrothermal treatment is expected to control the crystalline phase and microstructures of final BaTiO 3 powders.
