“…Ultralow frequency transducers were projected based on the face shear (or d 36 ) mode in PMN-PT crystals due to their ultralow frequency constant and high piezoelectric coefficients [376,377]. In addition, due to the uniqueness of the face shear vibration in combination with high coupling and high mechanical Q 36 , face shear crystals have been studied for tactile sensing and ultrasound motor applications [378–382]. In contrast to conventional thickness shear d 15 , the face shear vibration mode can be repolarized; i.e., the poling electrode is the same as the active electrode [141,340,374].…”

“…All these piezoelectric ultrasonic motors operating in friction drive mechanism at resonance exhibit quick response, high resolution in positioning, low profile, and high power density [513,516,517]. These motors usually adopt piezoelectric materials in the driving components, and operate at resonance for the maximum electric-to-mechanical energy conversion [382,518]. …”

“…However, for miniaturized USM designs working in non-continuous mode, the heat generation by the loss is not an issue, and hence relaxor-PT crystals can be used as a driving material because of their high dielectric constants and electromechanical couplings. Ci et al developed a standing wave PMN-PT single crystal ultrasonic linear motor operating in high-order face shear modes (FS-2 and FS-3 modes) and compared with a larger size piezo-ceramic motor [382].

“…Fig. 42 schematically shows the USM with motion trajectories of the two non-isomorphic in-plane face-shear vibration modes [382]. Face shear mode of the PMN-PT crystal was utilized for the USM design due to its prominent electromechanical coupling (0.77–0.83) and higher Q m (100–450).…”

Relaxor-PbTiO3 (PT) based ferroelectric crystals with the perovskite structure have been investigated over the last few decades due to their ultrahigh piezoelectric coefficients (d33 > 1500 pC/N) and electromechanical coupling factors (k33 > 90%), far outperforming state-of-the-art ferroelectric polycrystalline Pb(Zr,Ti)O3 ceramics, and are at the forefront of advanced electroacoustic applications. In this review, the performance merits of relaxor-PT crystals in various electroacoustic devices are presented from a piezoelectric material viewpoint. Opportunities come from not only the ultrahigh properties, specifically coupling and piezoelectric coefficients, but through novel vibration modes and crystallographic/domain engineering. Figure of merits (FOMs) of crystals with various compositions and phases were established for various applications, including medical ultrasonic transducers, underwater transducers, acoustic sensors and tweezers. For each device application, recent developments in relaxor-PT ferroelectric crystals were surveyed and compared with state-of-the-art polycrystalline piezoelectrics, with an emphasis on their strong anisotropic features and crystallographic uniqueness, including engineered domain - property relationships. This review starts with an introduction on electroacoustic transducers and the history of piezoelectric materials. The development of the high performance relaxor-PT single crystals, with a focus on their uniqueness in transducer applications, is then discussed. In the third part, various FOMs of piezoelectric materials for a wide range of ultrasound applications, including diagnostic ultrasound, therapeutic ultrasound, underwater acoustic and passive sensors, tactile sensors and acoustic tweezers, are evaluated to provide a thorough understanding of the materials’ behavior under operational conditions. Structure-property-performance relationships are then established. Finally, the impacts and challenges of relaxor-PT crystals are summarized to guide on-going and future research in the development of relaxor-PT crystals for the next generation electroacoustic transducers.

Continual precision actuations with nanoscale resolution over large ranges have extensive requirements in advanced intelligent manufacturing and precise surgical robots. To produce continual nanostep motion, conventionally, multiple pairs of piezo‐actuators are employed to operate in inchworm principle under complex three‐ or four‐phase timing signal drive. Inspired by the idea of ordered structures with functional units, a much simpler nanostep piezoelectric actuator consisting of (2 × 2) arrayed, cofired multilayer piezoceramic actuation units is developed, which operates in an artificially generated quasi shear mode (AGQSM) that is missing in natural piezoelectric ceramics. Under only one‐phase square‐wave voltage drive, the actuator can produce a stable, continual nanostep motion in two ways at nonresonant frequencies, and the obtained minimum step displacement is as low as 7 nm in open control, indicating its potential application as a precise finger or knife actuator in surgical robots. This work is of great guiding significance for future actuator designs using the methodology of ordered structure with piezoceramic actuation units and AGQSM.
