“…In [ 40 ], the authors use the finite element modeling method to fully calculate the self-bias of the ME effect in the bending mode. The finite element modeling method allows one to obtain only specific numerical results for the specified phase sizes of the ME composite.…”

“…An additional advantage is also the absence of lead (lead-free) in the sensor structure. It is of interest to discuss the methods for calculating self-biased structures that are known from publications of other authors [38][39][40]. In contrast to work [38], in which the authors use the hypothesis that the electric field strength is independent of the thickness coordinate z, when calculating the flexural mode of the ME effect, in this paper, as in [39], we used a more justified ratio for the size ratio of the investigated ME composite.…”

“…Along with the advantages of the considered sensors, their main drawback remained, namely that associated with the need to use a bias field, which is most often created by permanent magnets. This disadvantage was corrected in [ 36 , 37 , 38 , 39 , 40 , 41 ] by using gradient magnetostrictive–piezoelectric structures, since in this case it is possible to obtain an internal bias field of the composite without external additional devices. In the patent [ 36 ], it is shown that a magnetostrictive-ferroelectric structure with a gradient of magnetization and polarization makes it possible to obtain internal magnetic and electric fields that replace the external bias and polarizing fields.…”

“…The composite structures FeCuNbSiB/Ni/PZT with negative magnetostrictive Ni and FeCuNbSiB/FeNi/PZT with positive magnetostrictive FeNi were used to confirm the validity and reliability of the theoretical model. In [ 40 ] Zhang et al presented the results of studying the ME interaction in the structure of Terfenol-D (T), PZT-8H (P) and FeCuNbSiB (F), when the external DC magnetic field is zero. The developed theory based on the finite element method is highlighted with a direct comparison with experiments that show their close agreement.…”

The article is devoted to the theoretical and experimental study of a magnetoelectric (ME) current sensor based on a gradient structure. It is known that the use of gradient structures in magnetostrictive-piezoelectric composites makes it possible to create a self-biased structure by replacing an external magnetic field with an internal one, which significantly reduces the weight, power consumption and dimensions of the device. Current sensors based on a gradient bidomain structure LiNbO3 (LN)/Ni/Metglas with the following layer thicknesses: lithium niobate—500 μm, nickel—10 μm, Metglas—29 μm, operate on a linear section of the working characteristic and do not require the bias magnetic field. The main characteristics of a contactless ME current sensor: its current range measures up to 10 A, it has a sensitivity of 0.9 V/A, its current consumption is not more than 2.5 mA, and its linearity is maintained to an accuracy of 99.8%. Some additional advantages of a bidomain lithium niobate-based current sensor are the increased sensitivity of the device due to the use of the bending mode in the electromechanical resonance region and the absence of a lead component in the device.

“…Nonetheless, the efforts in theoretical understanding of the effective nonlinear response of three-phase magnetoelectric composites is quite limited with respect to that of the considering nonlinear constitutive behavior in each composite phase. A recent article by Zhang et al 22 , they theoretically studied the magnetoelectric effect of a three-phase layered magnetoelectric composite composed of Terfenol-D, PZT-8H and an inactive FeCuNbSiB layer with high magnetic conductivity. The phase constitutive law employed by Zhang et al 22 is nonlinear only for magnetostrictive constituent but is linear for piezoelectric material.…”

A computational method, dubbed simplified unit-cell micromechanics model, is generalized and applied to establish the effective nonlinear responses of three-phase magnetoelectric composites that are composed of two distinct magnetostrictive and piezoelectric phases embedded in elastic polymer matrices. The nature of nonlinear constitutive behavior of each constituent is expected to significantly influence the overall responses of the composites. To obtain the effective nonlinear responses, a mathematical linearization is first introduced to perform the constitutive linearization for the nonlinear materials, and the resulting constitutive equations are then unified and nested into the micromechanics model followed by iterations in order to minimize errors from the linearization process. For the purpose of comparison, we also reformulate the well-established Mori–Tanaka micromechanics model insofar as its mathematical structure is aligned with that of the simplified unit-cell model. Numerical results are first validated against limited experimental measurements available in literature. Parametric studies are then conducted in order to reveal the effect of phase constitutive laws, volume fractions, and geometries on the overall nonlinear responses of there-phase magnetoelectric composites. The contributions of this work complement those of earlier studies that prevalently devoted to two-phase magnetoelectric composites and linear magneto-electro-elastic coupled responses only.

Self‐biased magnetoelectric composite for energy harvesting

View full text Add to dashboard Cite

The wireless sensor network energy supply technology for the Internet of things has progressed substantially, but attempts to provide sustainable and environmentally friendly energy for sensor networks remain limited and considerably cumbersome for practical application. Energy harvesting devices based on the magnetoelectric (ME) coupling effect have promising prospects in the field of self‐powered devices due to their advantages of small size, fast response, and low power consumption. Driven by application requirements, the development of composite with a self‐biased magnetoelectric (SME) coupling effect provides effective strategies for the miniaturized and high‐precision design of energy harvesting devices. This review summarizes the work mechanism, research status, characteristics, and structures of SME composites, with emphasis on the application and development of SME devices for vibration and magnetic energy harvesting. The main challenges and future development directions for the design and implementation of energy harvesting devices based on the SME effect are presented.
