“…Harvesting this weak and low-frequency magnetic noise (< 1 mT = 10 G) to develop a consistent electricity source remains a difficult challenge. Over the last decade, Ryu group [47,94,95] and other researchers [96][97][98][99][100][101][102][103][104][105] have investigated methods to obtain optimum electricity from the tiny magnetic fields in the surroundings, using magneto-mechano-electric (MME) mechanism. The operation mechanism can be described as follows: When the ME composite is placed in an AC magnetic field, the magnetostrictive layer in the composite responds to the mechanical vibration (magneto-mechano coupling), thereby straining the piezoelectric layer, which results in an output voltage across the electrical load through the direct piezoelectric effect (mechano-electric coupling).…”

Multiferroic magnetoelectric (ME) composites are attractive materials for various electrically and magnetically cross-coupled devices. Many studies have been conducted on fundamental understanding, fabrication processes, and applications of ME composite material systems in the last four decades which has brought the technology closer to realization in practical devices. In this article, we present a review of ME composite materials and some notable potential applications based upon their properties. A brief summary is presented on the parameters that influence the performance of ME composites, their coupling structures, fabrications processes, characterization techniques, and perspectives on direct (magnetic to electric) and converse (electric to magnetic) ME devices. Overall, the research on ME composite systems has brought us closer to their deployment.

The concept of magneto-mechano-electric (MME) energy conversion has been demonstrated using a magnetoelectric (ME) composite, with cantilever structure working at resonating mode, to reliably covert low-frequency magnetic noise fields to electric power. [19,20] This process is the result of multiple energy transductions starting from magnetic energy to mechanical energy and then to electrical energy. An MME generator is known to be more efficient than an electromagnetic generator at a small scale in a low frequency magnetic field. A serious of rationally designed MME generators with piezoelectric single crystals had shown great potential for scavenging weak and irregular magnetic energy. [19][20][21][22] The harvesting performance of piezoelectric-based energy harvesters is directly related to the product of the piezoelectric strain constant, d ij and the piezoelectric voltage constant, g ij (the mathematical product of which is called the figure of merit: FOM = d ij × g ij ), under constant applied stress. [19] However, recent investigations have determined that FOM could not explain completely the output performance of such energy harvesters. [19,23] This is because the hysteresis (or non-linearity) of the piezoelectric materials is related to losses such as dielectric loss (inverse of electrical quality factor) and mechanical loss (inverse of mechanical quality factor); and consequently, performance degradation of the device. Therefore, to improve the harvesting performance, it is important to know how the loss factors affect the harvested output power in MME generators.To provide the answer, various piezoelectric PMN-PZT single crystal thin sheets; namely, high-loss PMN-PZT, medium-loss PMN-PZT, and low-loss PMN-PZT with the typical rhombohedral perovskite phase close to the morphotropic phase boundary (MPB), were grown using the solid-state-crystal growth (SSCG) method (see Data S1 in the Supporting information). This greatly improved the desired properties. In this study, we fabricated three MME generators using ME composites with these PMN-PZT single crystalline materials in macro-fibers form, and a magnetostrictive Ni plate. In this paper, the MME generators embedded with high-loss PMN-PZT, medium-loss PMN-PZT, and low-loss PMN-PZT, were identified as highloss, medium-loss, and low-loss (respectively) MME generators. Using them, we eventually succeeded in finding a way to extract significantly improved electric power sufficient to realize a self-powered energy device. Variation in the properties of the piezoelectric PMN-PZT single-crystal macro-fibers (SCMFs) results in a substantial change in the output voltage, the energy harvesting characteristics, and the power density of the device.We are entering an era when electrical energy scavenged from the irregular energy resources that are found ubiquitously in our living environment (e.g., light, vibrations, motion, heat, and magnetic fields) can be used to operate small electronic devices that do extraordinary tasks.

“…Whereas, Xing et al [14][15][16] proposed a distinctive type of ME composite constructed by a piezobimorph and magnet, in which giant ME effect was realized by magneto-mechano-electric (MME) coupling, i.e., the interaction coupling of magnetic torque and piezoelectricity. Following that work, Liu et al [17][18][19] further investigated and developed this type of MME composite and obtained colossal ME effect in composite of a piezofiber/copper bender and magnet. Here, we further study a piezo-unimorph/magnet composite and present the corresponding theoretical model, which was not investigated in previous reports.…”

A magneto-mechano-electric coupling equivalent circuit of piezoelectric bimorph/magnets composite cantilever J. Appl. Phys. 115, 084112 (2014); 10.1063/1.4867177Energy harvesting from ambient low-frequency magnetic field using magneto-mechano-electric composite cantilever Appl. Phys. Lett.The low frequency magneto-mechano-electric (MME) coupling behavior in the piezo-unimorph/magnet composites has been investigated. A theoretical model on the low frequency MME coupling behaviors for the piezo-unimorph/magnet composite was proposed. The experimental results coincided with the corresponding theoretical prediction and proved the validity of the theoretical model. Based on the theoretical model, the dependencies of the magnetoelectric voltage coefficients on the geometrical parameters of the piezo-unimorph/magnet composite were numerically calculated. The results show that there are optimal geometrical parameters of the piezo-unimorph/magnet composite for achieving maximum ME voltage coefficients. This research gives a theoretical basis to understand the low frequency MME coupling behaviors in the piezo-unimorph/magnet composite and provides a theoretical approach for optimal design of MME devices based on this configuration.
