“…There are four basic operational modes that need to be considered for 1D ME laminated sensor modeling. 7,18 These are classified by the direction of the sensed magnetic field and polarized electric field. The "L-L" mode defines longitudinal magnetic field and longitudinal polarized electric field axes directed along the long axes of the laminate.…”

“…[14][15][16][17] So, we have used this assumption for our modeling. On the basis of the linear piezoelectric and magnetostrictive constitutive equations, an ME laminated sensor can be represented by an equivalent circuit, 7,18,19 where the magneto-elastic coupling and elasto-electric coefficients are mimicked by an ideal transformer. Furthermore, the voltage or charge coefficients can be determined using the piezoelectric, magnetostrictive, elastic compliance, and permeability constants, and the relative volume factor of layers.…”

The equivalent magnetic noise spectral density level for long type magnetostrictive-piezoelectric laminated composites has been investigated by using a 1D equivalent circuit model, and exemplified for a longitudinal-transverse mode. The theoretical developments explain well our experimental results. The findings show that similar ultimate magnetic noise spectral noise density can be expected whether using either charge or voltage amplifier detection methods. The findings show that a volume effect and the dielectric loss factor of the piezoelectric layer are the dominant sources of the noise floor. Our findings show that the noise scales as 1/√f. The lowest equivalent noise floor value that has been observed is 10/√f pT/√Hz for f ≪ 10 kHz, with a white noise level of 100 fT/√Hz above 10 kHz.

This paper investigates the performance of magnetoelectric composites composed of multilayer magnetostrictive and piezoelectric laminates in which the series and parallel electrical connections are applied. The multiphysics simulations have been performed according to the different longitudinal and transversal magnetization and polarization modes using a numerical model based on the finite element method and an analytical formulation based on the equivalent circuit model. The obtained results highlight the limitation of the analytical formulation to model the multilayer composites when an alternative opposing polarization between each neighboring piezoelectric layer is applied.
