“…Additionally, the change in the phosphorous content altered the resonant frequency of the cylindrical ME sample due to change in inherent parameters such as average density and equivalent elastic compliance, which directly influence the resonant frequency. In a bid to further boost the ME output, a multi-electrode system was employed in trilayered cylindrical plated composites such that the circular electrode along the circumference was segregated into four arched electrodes [114]. A three-fold increase in ME performance was observed in the case of multi-electrode composite over a single electrode system.…”

Layered or 2-2 conﬁguration magnetoelectric (ME) composites have gained signiﬁcant interest in the last few decades owing to their ease of fabrication and relatively high ME output realizable at room temperature. Conventionally, layered ME composites are fabricated by bonding the constituent magnetostrictive and piezoelectric layers via an epoxy or adhesive. Thus, the epoxied interface acts as the medium of strain transfer between the constituent layers resulting in the ME effect. However, the presence of epoxy makes the composite prone to limitations such as reduced device life due to aging epoxy, reduced strain transfer efﬁcacy due to low stiffness of epoxy, and degradation of composite properties at elevated temperatures due to the low glass transition temperature of epoxy material. Thus, various epoxy-free methods for layered or 2-2 type ME composite fabrication have been developed in the last two decades to circumvent these limitations. These methods include co-ﬁring technique, electroless deposition, electrodeposition, shrink-ﬁt, and press-ﬁt. Each of these methods has tried to mitigate the disadvantages of its predecessors, however posing its own set of limitations. This review article captures the evolutionary journey of the development of each of these aforementioned techniques in a chronological sequence by highlighting the advantages and disadvantages offered by each of them. Subsequently, a brief overview of state of the art has been provided in summary, followed by a discussion on the potential avenues that may be probed further to improve the available epoxy-free fabrication techniques for layered or 2-2 ME composites.

Strain-mediated multiferroic composite structures are gaining scientific and technological attention because of the promise of low power consumption and greater flexibility in material and geometry choices. In this study, the direct magnetoelectric coupling coefficient (DME) of composite multiferroic cylinders, consisting of two mechanically bonded concentric cylinders, was analytically modeled under the influence of a radially emanating magnetic field. The analysis framework emphasized the effect of demagnetization on the overall performance. The demagnetization effect was thoroughly considered as a function of the imposed mechanical boundary conditions, the geometrical dimensions of the composite cylinder, and the introduction of a thin elastic layer at the interface between the inner piezomagnetic and outer piezoelectric cylinders. The results indicate that the demagnetization effect adversely impacted the DME coefficient. In a trial to compensate for the reduction in peak DME coefficient due to demagnetization, a non-dimensional geometrical analysis was carried out to identify the geometrical attributes corresponding to the maximum DME. It was observed that the peak DME coefficient was nearly unaffected by varying the inner radius of the composite cylinder, while it approached its maximum value when the thickness of the piezoelectric cylinder was almost 60% of the total thickness of the composite cylinder. The latter conclusion was true for all of the considered boundary conditions.

“…In addition to rectangular laminated structures, ME composites have other structures, such as cylindrical structures [27] and circular nested structures [28].

Magnetoelectric (ME) composites have been proved to be applicable to current sensors. However, the previously reported ME materials-based current sensors mainly focus on direct current and sine alternating current sensing, which put a critical limit on the measurement of transient current. In this paper, a cylindrical ME composite consisting of a magnetostrictive Fe83Ga17 (FeGa) cylinder and a piezoelectric Pb(Zr,Ti)O3 (PZT) circular tube is fabricated for lightning current sensing applications. The time-domain output voltage of the FeGa/PZT composite is simulated and measured in detail. Under the excitation of 8/20µs lighting current, the output voltage of the composite can change with the current. But the damping oscillation at its resonant frequency is observed. Furthermore, to obtain an obvious ME response, the FeGa/PZT cylinder and current-carrying wire should be arranged closely and in an orthogonal way. When the amplitude of 8/20µs lightning current is in the range of 500A to 9kA, the ME FeGa/PZT composite shows a sensitivity of 1.36mV/A, a linear response (R2=0.9993), and a small return error (0.12V). These results provide that the ME composite is suitable to be used in non-contact lightning current measurement.
