“…This review [9][10][11] [ [12][13][14][15] This review [5] [ 5,8] Magnetostriction rested aside for about one century without any effective technological fall-out, until new rare earth-based materials came into play. In the late 1950s and early 1960s, a consistent attention was devoted to the study of rare earth elements [16], observing that rare earths, such as single crystals Dysprosium (Dy) [17] and Terbium (Tb) [18], exhibited large magnetostriction (≈8000 ppm) [19].…”

“…Generally speaking, the experimental setup to characterize the magnetostrictive material has the same elements reported in Figure 1. The magnetostrictive sample (1) is placed in a magnetic path (5), made of bulky iron elements or iron sheets (for better dynamic performances), and is wrapped by a pickup coil (2). The magnetic circuit provides the field in the sample axis direction with an excitation coil (3), which could be wounded around the pickup coil or suitably placed on one or more branches of the magnetic path.…”

“…The direct (Joule) effect implies a conversion from magnetic to mechanical energy and is exploited for actuation purposes, subject of this review. Other manifestations named apart include the Wiedemann effect [4], which is the twisting of a magnetostrictive cylinder when simultaneous longitudinal and circumferential magnetic fields are applied to the material [5], while the less known Matteucci effect [6] may be considered the inverse of Wiedemann and is the arise of a helical magnetization vector, i.e., the superposition of an axial and a circular vector, when a torsion is applied to the magnetostrictive sample and is widely exploited in amorphous wires [7,8]. These effects are sketched in Table 1 with references to the main review papers about the respective effect.…”

“…Another wide review on energy harvesting, including the magnetostrictive based [14], is found in [13]. A short review of magnetostrictive transducers based on the (reversed) Wiedemann effect, specially intended for Non Destructive Evaluations (NDE), is presented in [5], while a review of magnetostrictive patch transducers for ultrasonic nondestructive testing is presented in [67]. A review of applications related to Matteucci effect is presented in [8].…”

Magnetostrictive actuators play an important role in the perception of usefulness of smart materials and devices. Their applications are potentially wider than that of piezoelectric actuators because of the higher energy density and intrinsic robustness. However, the non-negligible hysteresis and complexity of their characteristics make the design and control quite difficult and has limited their diffusion in industrial applications. Nevertheless, the scientific literature presents a wide offer of results in design and geometries, modeling and control that may be exploited for applications. This paper gives a reasoned review of the main results achieved in the literature about design, modeling and control of magnetostrictive actuators exploiting the direct effects of magnetostriction (Joule and Wiedemann). Some perspectives and challenges about magnetostrictive actuators development are also gathered.

Development of an omni-directional shear horizontal mode magnetostrictive patch transducerThe application of guided waves for the testing of plate-type structures has been recently investigated by a number of research groups due to the ability of guided waves to detect corrosion in remote and hidden areas. Guided wave sensors for plate applications can be either directed (i.e., the waves propagate in a single direction) or omnidirectional. Each type has certain advantages and disadvantages. Omnidirectional sensors can inspect large areas from a single location, but it is challenging to define where a feature is located. Conversely, directed sensors can be used to precisely locate an indication, but have no sensitivity to flaws away from the wave propagation direction. This work describes a newly developed sensor that combines the strengths of both sensor types to create a novel omnidirectional transducer. The sensor transduction is based on a custom magnetostrictive transducer (MsT). In this new probe design, a directed, plate-application MsT with known characteristics was incorporated into an automated scanner. This scanner rotates the directed MsT for data collection at regular intervals. Coupling of the transducer to the plate is accomplished using a shear wave couplant. The array of data that is received is used for compiling B-scans and imaging, utilizing a synthetic aperture focusing algorithm (SAFT). The performance of the probe was evaluated on a 0.5-inch thick carbon steel plate mockup with a surface area of over 100 square feet. The mockup had a variety of known anomalies representing localized and distributed pitting corrosion, gradual wall thinning, and notches of different depths. Experimental data was also acquired using the new probe on a retired storage tank with known corrosion damage. The performance of the new sensor and its limitations are discussed together with general directions in technology development.

The development of ultrasonic‐guided wave sensors is of great significance for structural health monitoring (SHM). In this work, a shear horizontal (SH) ultrasonic guided wave sensor based on the Ca3TaGa3Si2O14 (CTGS) piezoelectric single crystal is demonstrated. The findings reveal that the CTGS‐based ultrasonic guided wave sensor is proficient in transmitting and receiving pure fundamental SH wave (SH0 wave) along two orthogonal main directions (0° and 90°) over a wide frequency range (100–350 kHz), exhibiting strong response to the SH0 wave. Under the driving voltage of 100 V, the peak‐to‐peak values of the sensor output are 110.8 and 8.0 mV at room temperature and high temperature of 600 °C, respectively. Additionally, the signal‐to‐noise ratio (SNR) of the CTGS‐based SH0 sensor is evaluated to be >18.9 dB even at the elevated temperature of 600 °C. Moreover, the CTGS‐based SH0 sensor showcases its reasonable defect localization ability at temperatures up to 600 °C, demonstrating its great potential for application in the high temperature in‐situ SHM.
