“…To ensure that TrFE/NFO 0–3 nanocomposites can successively convert surrounding minuscule magnetic noise into electric power, ME analysis should be performed. The ME effect of the nanocomposites was measured by the dynamic method at room temperature, which involves a superimposed condition of alternating magnetic field ( h ac ) with a constant ( H dc ) magnetic field (Figure a) . The magnetoelectric output voltage ( V 0 ) and eventually magnetoelectric coupling coefficients were measured where t is the thickness of the sample.…”

“…A Quantum Design Physical Properties Measurement System (PPMS) was used to determine the magnetic properties. The magnetoelectric measurements were carried out by well-established homemade setup, following the dynamic method [17]. The output voltage of the harvester was recorded with a digital storage oscilloscope (Agilent DSO3102A).…”

“…NFO is generally used as a promising magnetostrictive material due to its suitable magnetostriction, reasonable permeability, low coercivity, and high resistance, which make it useful in magnetoelectric applications. Although ME effects of PVDF/CFO and P(VDF-TrFE)/CFO composites have been extensively studied, the P(VDF-TrFE)/NFO 0–3 nanocomposite with nanoparticle dimensions down to 10 nm has been rarely studied. ,,, …”

Perhaps the most abundant form of waste energy in our surrounding is the parasitic magnetic noise arising from electrical power transmission system. In this work, a flexible and rollable magneto-mechano-electric nanogenerator (MMENG) based wireless IoT sensor has been demonstrated in order to capture and utilize the magnetic noise. Free standing magnetoelectric composites are fabricated by combining magnetostrictive nickel ferrite (NiFe 2 O 4 ) nanoparticles and piezoelectric polyvinylidene-co-trifluoroethylene (P(VDF-TrFE)) polymer. The magnetoelctric 0-3 type nanocomposites possess maximum magnetoelectric voltage co-efficient (α) of 11.43 mV/cm-Oe. Even, without magnetic bias field 99 % of the maximum value is observed due to self-bias effect. As a result, the MMENG generates peak-to-peak open circuit voltage of 1.4 V, output power density of 0.05 µW/cm 3 and successfully operates commercial capacitor under the weak (⁓ 1.7× 10 -3 T) and low frequency (⁓ 50 Hz) stray magnetic field arising from the power cable of home appliances such as, electric kettle. Finally, the harvested electrical signal has been wirelessly transmitted to a smart phone in order to demonstrate the possibility of position monitoring system construction. This cost effective and easy to integrate approach with tailored size and shape of device configuration is expected to be explored in nextgeneration self-powered IoT sensors including implantable biomedical devices and human health monitoring sensory systems.

“…A Hall probe placed next to the sample measures the intensity of the DC bias field. The field typically takes values from a range of ±15 kOe (1 Oe = 79.577 Am -1 in SI units) [7,11,18,28]. The Helmholtz coils connected to a function generator generate an AC field at frequency f (usually up to 10 kHz) and intensity of about 20 Oe.…”

Magnetoelectric multiferroics are solid-state materials which exhibit a coupling between ferroelectric and magnetic orders. This phenomenon is known as the magnetoelectric (ME) effect. Multiferroic materials possess a wide range of potential applications in such fields as metrology, electronics, energy harvesting & conversion, and medicine. Multiferroic research is facing two main challenges. Firstly, scientists are continuously trying to obtain a material with sufficiently strong, room-temperature ME coupling that would enable its commercial application. Secondly, the measurement techniques used in multiferroic research are often problematic to implement in a laboratory setting and fail to yield reproducible results. The aim of the present work is to discuss three most commonly used methods in multiferroic studies; the lock-in technique, the Sawyer-Tower (S-T) circuit and dielectric constant measurements. The paper opens with a general description of multiferroics which is followed by mathematical representation of the ME effect. The main body deals with the description of the aforementioned measurement techniques. The article closes with a conclusion and outlook for future research.
