Relaxor-PbTiO 3 piezoelectric single crystals have been widely used in a broad range of electromechanical devices, including piezoelectric sensors, actuators, and transducers. This paper reviews the unique properties of these single crystals for piezoelectric sensors. Design, fabrication and characterization of various relaxor-PT single crystal piezoelectric sensors and their applications are presented and compared with their piezoelectric ceramic counterparts. Newly applicable fields and future trends of relaxor-PT sensors are also suggested in this review paper.

“…They have come into prominence due to their extrahigh electromechanical coupling factor, piezoelectric and dielectric coefficients, and field induced strain response. [1][2][3] Most oxygen-octahedral ferroelectrics, which exhibit excellent electromechanical properties, also have outstanding optical properties. 4,5 Although lots of work on the dielectric and piezoelectric properties of PMN-xPT single crystals have been done, the values of the optical properties are not perfectly known.…”

The refractive indices and extinction coefficients were obtained. The modified Sellmeier equations for the refractive indices were obtained by least-squares fit. The equations can be used to calculate the refractive index with high accuracy in the low absorption wavelength range, namely, from 400 to 5800 nm. The Sellmeier optical coefficients E 0 , 0 , S 0 , and E d were calculated by fitting the single-term oscillator equation. They are related directly to the electronic energy band structure and have the physical significance. The optical band gap energies were also obtained from absorption coefficient spectra. Our results show that as the PT content increases, the refractive index of PMN-xPT single crystals increases, while the optical band gap energy decreases. Some discussions about the BO 6 octahedron building block that determines the basic energy level of PMN-xPT single crystals are also presented in this article.

“…In the past decade, relaxor-based ferroelectric single crystals Pb(Mg 1/3 Nb 2/3 )-PbTiO 3 (PMN-PT) and Pb(Zn 1/3 Nb 2/3 )-PbTiO 3 (PZN-PT) have attracted considerable attention because of their extremely high piezoelectric and electromechanical coupling coefficients near the morphotropic phase boundary (MPB) composition (d 33 ≈ 2000 pC/N, k 33 ≈ 0.92). [3][4][5] Researches on PMN-PT and PZN-PT single crystals have been carried out in the field of medical ultrasonic applications and some attractive results have been found. [6][7][8][9] Single crystal piezoelectrics have brought out a revolutionary development for ultrasonic transducers in modern medical ultrasonic imaging systems.…”

(PIN-PMN-PT) single crystal was investigated for potential application in ultrasonic linear array. Orientation and temperature dependences of height extensional electromechanical coupling coefficient k 33 for PIN-PMN-PT single crystal were studied. It was found that the [001] poled PIN-PMN-PT diced along the [100] direction would achieve a maximum k 33 (∼87%) and the service temperature was up to 110• C. Ultrasonic linear arrays using PIN-PMN-PT single crystal and PZT ceramic were fabricated and compared. The bandwidth at −6 dB, two-way insertion loss and pulse length of the PIN-PMN-PT array were 98.6%, −45.1 dB, and 0.28 μs, respectively, which were about 25% broader, 3.7dB higher, and 0.08 μs shorter than those of the PZT array. The experimental results agreed well with the theoretical simulation. These superior performances were attributable to the excellent piezoelectric properties of PIN-PMN-PT single crystal.
