Summary: Magneto-mechano-electric (MME) generator converts magnetic energy into electrical energy via mechanical strain/stress mediated magnetoelectric coupling effect. In this work, a hybrid multi-mode MME device is proposed with broadened bandwidth and enhanced energy harvesting performance by developing the constitutive equation of MME structure. The designed hybrid generator includes three power generation units: piezoelectric energy harvesting (PEH) unit, electromagnetic energy harvesting (EEH) unit, and magnetostrictive energy harvesting (MEH) unit. Moreover, the corresponding energy harvesting management circuit is designed for these units to achieve the maximum harvest of magnetic field energy. At the magnetic field of 5.57 Oe, the maximum output power of the three generating units are 0.71 mW (PEH), 1.694 mW (EEH), and 0.27 mW (MEH), respectively. The proposed hybrid generator can provide a stable power for temperature and humidity sensors integrated with Bluetooth wireless communication technology by harvesting stray magnetic field energy, and has the potential to power wireless sensors.

Summary: We investigated the magneto-mechano-electric (MME) response of (2-2) layered magnetostrictive-piezoelectric composite structures. The BCTZS piezoceramics exhibited excellent piezoelectric properties and coexistence of orthorhombic-tetragonal lattice symmetries. The CNFO magnetostrictive phase showed a significant piezomagnetic coefficient. The CNFO/BCTZS/CNFO structure demonstrated a strong magnetoelectric (ME) response and resonant enhancement in ME coupling.

Summary: Understanding strain gradient phenomena is crucial in areas like condensed matter physics. It can enhance coupling effects in composites of piezoelectric or ferroelectric materials with magnetostrictive phases, and potentially lead to the development of new functional multiferroic composites or magnetic-field-driven flexoelectric/magnetostrictive platforms. Generating strain gradients by applying magnetic or electric fields in materials with non-fully constrained geometries can ultimately result in high flexomagnetoelectric effects.

Summary: The strain-driven interfacial coupling between ferromagnetic and ferroelectric constituents in magnetoelectric (ME) composites makes them potential candidates for novel multifunctional devices. ME thin-film devices have shown promising applications, with (Pb1-xZrx)TiO3 (PZT), Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PMN-PT), Aluminium nitride (AlN), and Al1-xScxN as commonly used piezoelectric constituents, and FeGa, FeGaB, FeCo, FeCoB, and Metglas as commonly used magnetostrictive constituents. ME field sensors offer a limit of detection in the fT/Hz(1/2) range at the mechanical resonance frequency, with noise floors of 1-100 pT/Hz(1/2) at 1 Hz. ME antennas operate at very-high frequency and ultra-high frequency ranges, and have potential applications in biomedical devices and wearable antennas. Integrated tunable inductors and band-pass filters, along with miniaturized ME energy harvesters, are also discussed.
