“…It can be inferred that the lower-frequency resonant peak at 10.2 kHz corresponds to the bending vibration mode (α ME,B , ME voltage coefficient in bending vibration mode), while the higherfrequency resonant peak at 51.15 kHz corresponds to the longitudinal vibration mode (α ME,L , ME voltage coefficient in longitudinal vibration mode), which also aligns with previous research findings. 20,[23][24][25][26]45 The two resonance frequencies of the vacuum-treated samples (blue line) are 10.59 and 51.0 kHz, corresponding to ME voltage coefficients of 493.7 V• cm −1 •Oe −1 (α ME,B ) and 93.4 V•cm −1 •Oe −1 (α ME,L ). In comparison to the untreated samples, the vacuum-treated samples demonstrate a nearly 2.5-fold increase in the maximum ME voltage coefficient.…”

“…The results indicated that the resonance frequency decreased with increasing room temperature, albeit at a slow rate. According to the calculation formula of resonance frequency for a rectangular ME bilayered structure, the bending vibration frequency is much lower than the longitudinal resonance frequency. ,− Inspired by this, some researchers have tried to make ME sensors operate at the bending vibration frequency. They conducted an in-depth theoretical study of asymmetric ME laminated composites with predominantly bending vibration modes in a low-frequency range. ,, Unfortunately, a comparison of their ME voltage coefficients determined that the performance in bending vibration modes was poorer than that in longitudinal vibration modes, , and making ME sensors work at the bending vibration frequency mode also leads to a decrease in sensor sensitivity.…”

The bending vibration modes of asymmetric magnetoelectric (ME) laminated composites operate in a lowfrequency range, but the small value of the ME voltage coefficient (α ME ) at bending vibration frequencies currently hinders the application of ME magnetic sensors at lower frequencies. In this study, poly(vinylidene fluoride) (PVDF) and Metglas were combined by adhesive bonding method to manufacture laminated ME composites. The average stiffness of ME composites was reduced by using vacuum packing technique to modulate the dominant vibration mode from longitudinal to bending. After treatment, the dominant resonance frequency and the DC bias field of the samples with a length of 30 mm were reduced from 51.15 kHz and 3.7 Oe to 10.59 kHz and 2.35 Oe, respectively. The α ME of the samples was significantly increased to 493.7 V•cm −1 •Oe −1 , which is approximately 2.5 times higher than that of the untreated samples. Remarkable magnetic sensing capabilities at low frequencies of the treated samples were also were found. At 10.59 kHz, the samples had a large sensitivity of 2522.33 mV•Oe −1 , an excellent linearity of 0.99985, and good resolutions of 0.4 nT for AC and 2.4 nT for DC magnetic fields, respectively. In addition, samples of different sizes were prepared for comparison. The experimental results obtained from these samples were consistent with those of the original samples. These findings highlight the effectiveness of reducing the average stiffness of composites through the vacuum packing technique in reducing the resonance frequency, optimizing the bias field, and increasing the α ME value. This technique provides a valuable approach to the development of low-frequency and highly sensitive magnetic field sensors.

“…And the geometry and size of the composites determine the excitation and frequency selection of resonant modes. [127][128][129] Swain et al discussed in detail the relationship between the resonance frequency and operating mode in a BZT-BCT/NFO leadfree bonded ME composite.

“…The ME coupling at the natural frequency of piezoelectric or piezomagnetic phases shows that the cross‐coupling is greatly strengthened (two orders of magnitude amplification) under these conditions because the strain transfer becomes greater than detuning or nonresonant frequency. And the geometry and size of the composites determine the excitation and frequency selection of resonant modes 127–129 .

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.

“…When a magnetic field is applied to ME composites, their ferromagnetic layers shrink or stretch due to the magnetostrictive effect; then, the resulting strain/stress is transferred to the piezoelectric material, leading to a voltage change [2]. Devices based on laminated ME structures have shown promising potential for use in magnetic sensors, acoustically driven antennas and power conversion devices due to their high energy conversion efficiency [1][2][3][4][6][7][8][9][10][11].…”

Understanding the correlation between magnetomechanical coupling factors (k) and damping factors (Q−1) is a key pathway toward enhancing the magnetomechanical power conversion efficiency in laminated magnetoelectric (ME) composites by manipulating the magnetic and mechanical properties of Fe-based amorphous metals through engineering. The k and Q−1 factors of FeSiB amorphous ribbons annealed in air at different temperatures are investigated. It is found that k and Q−1 factors are affected by both magnetic and elastic properties. The magnetic and elastic properties are characterized in terms of the magnetomechanical power efficiency for low-temperature annealing. The k and Q−1 of FeSiB-based epoxied laminates with different stacking numbers show that a −3 dB bandwidth and Young’s modulus are expressed in terms of the magnetomechanical power efficiency for high lamination stacking.
