“…Piezoelectric materials can convert mechanical energy into electrical energy or vice versa and have been applied to diverse electronic devices, including piezoelectric actuators, ultrasonic transducers, and piezoelectric energy harvesters [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Until recently, Pb(Zr, Ti)O 3 (PZT)-modified ceramics were widely utilized to fabricate piezoelectric components because of their excellent piezoelectric properties and high Curie temperatures ( T C ), allowing them to control the piezoceramics markets [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ].…”

(K0.5Na0.5)NbO3 (KNN)-based ceramics have been extensively investigated as replacements for Pb(Zr, Ti)O3-based ceramics. KNN-based ceramics exhibit an orthorhombic structure at room temperature and a rhombohedral–orthorhombic (R–O) phase transition temperature (TR–O), orthorhombic–tetragonal (O–T) phase transition temperature (TO–T), and Curie temperature of −110, 190, and 420 °C, respectively. Forming KNN-based ceramics with a multistructure that can assist in domain rotation is one technique for enhancing their piezoelectric properties. This review investigates and introduces KNN-based ceramics with various multistructures. A reactive-templated grain growth method that aligns the grains of piezoceramics in a specific orientation is another approach for improving the piezoelectric properties of KNN-modified ceramics. The piezoelectric properties of the [001]-textured KNN-based ceramics are improved because their microstructures are similar to those of the [001]-oriented single crystals. The improvement in the piezoelectric properties after [001] texturing is largely influenced by the crystal structure of the textured ceramics. In this review, [001]-textured KNN-based ceramics with different crystal structures are investigated and systematically summarized.

“…Because of the environmental protection and biocompatibility, lead-free ferroelectric materials − especially Na 0.5 Bi 0.5 TiO 3 (NBT) , are considered to be an excellent candidate for piezoelectric materials because of its strong piezoelectric properties with relatively large remanent polarization at room temperature . On the other hand, with the rapid development of contemporary science and technology to the nanometer field and the trend of miniaturization of device sizes, researchers have conducted many experiments in ferroelectric materials such as thin films, nanowires, nanofibers, and nanotubes .…”

Piezoelectric and ferroelectric properties of lead-free sodium bismuth titanate Na 0.5 Bi 0.5 TiO 3 (NBT) nanotube arrays were studied using piezoresponse force microscopy. The nanotube arrays prepared by sol filling in the porous anodic aluminum oxide template with an exposure height of 30−55 nm and vertical arrangement demonstrated enhanced piezoelectric properties compared with the other nanotube structures and a large piezoelectric coefficient with regular domain states. We further prepared a metal/NBT nanotube arrays/metal capacitor for the study of ferroelectric and piezoelectric properties. The piezoelectric properties of NBT nanotube arrays were found to be much improved in a capacitor and finite element modeling attributes such improvement to the uniform electric potential distribution from the tip of the nanotube in the capacitor. The improved piezoelectric properties could make NBT nanotube arrays as a promising candidate for piezoelectric nanostructure devices.
