“…58,135 Similarly, a five-layer composite FeCoV/ Terfenol-D/PZT/Terfenol-D/FeCoV exhibits an evident magnetic hysteresis at zero-bias field and a resonant α SME of 19.6 V cm −1 Oe −1 , which is 1.75 times that of conventional three-layer Terfenol-D/PZT/Terfenol-D laminate composite. 147 Theoretically, Gao and coworkers 153 discussed the effect of working temperature and prestress on the SME coupling of a FeCuNbSiB/Terfenol-D/PZT/Terfenol-D/ FeCuNbSiB composite. Prestress negatively influenced SME coupling and evidently changed the effect of temperature on the zero-bias ME voltage.…”

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.

“…Although the strain of the magnetostrictive layer under the magnetic field is larger than that of the traditional ferromagnetic material, in the composite component, the strain transferred to the piezoelectric material is limited and still in the linear elasticity range. The piezoelectric constitutive equations in the strain-charge form are expressed in equations ( 9) and (10) [41]:…”

Magnetostrictive materials with good mechanical properties can effectively convert the alternating magnetic energy in the environment into mechanical vibrations via the magnetostriction effect. However, in previous studies, there are few discussions on the comprehensive mechanism of different magnetic field environments on magnetoelectric composite components. This paper firstly analyzed the variation rules of typical parameters in the magneto-electromechanical conversion process of two types of magnetoelectric composite components under the action of DC bias magnetic field and DC - AC dual magnetic field in detail by using COMSOL software. Then, we actually made two kinds of magnetoelectric composite components and verified the validity of the theoretical analysis through the self-built experimental system, and tested their performance in energy harvesting. The experimental results show that, under a harmonic excitation of 3 Oe magnetic field, the DC bias magnetic field of 120 Oe can increase the open-circuit voltage of the Galfenol alloy based piezoelectric cantilever from 0.495V to 10.68V, and the output power from 1.6μW to 42μW by 2525% with a matched external load of 50kΩ. Under the action of 100Oe DC bias magnetic field and 3Oe AC magnetic filed, the open-circuit voltage of nickel component increases from 0.117V to 0.837V, and the output power increases from 2.6μW to 23μW by 784.6% under the adaptation of 1000kΩ external resistance. The findings of this work reveal the effect of the coupled magnetic field for the magnetostriction for different materials and provide the guideline for the design of magnetostrictive energy harvesters.
