Computation of the Induced Current Density Into the Human Body Due to Relative LF Magnetic Field Generated by Realistic Devices

Abstract

A three-dimensional finite-element formulation to compute induced currents into the human body due to relative low-frequency magnetic field is described. Magnetic source field and induced currents are computed separately, allowing to handle sources due to realistic devices. This method is validated using analytical solutions over a sphere. The limit of validity of the formulation is established. Computations using an accurate model of the human body are presented.Index Terms-Bioelectric phenomena, dosimetry, quasi-static magnetic fields, three-dimensional (3-D) finite-element methods.

A Touch Sensing Technique Using the Effects of Extremely Low Frequency Fields on the Human Body

“…Therefore, a quasi-static approximation can be used, and the effects of the external electric and magnetic fields on the human body can be computed independently [31]. The magnetic permeability of the human body is similar to that of free space [32]. As a consequence, the magnetic field’s effect on the human body can be neglected, when considering indoor applications.…”

Computation of Induced Fields Into the Human Body by Dual Finite Element Formulations

“…where b s is the imposed flux density to whi the body is exposed. e computational domain can thus be restried to the human body [15] with an imposed boundary condition at its surface given by: n · j| ∂Ω = 0. At the continuous level, these fields (together with associated potentials-see below) can be organized in the following Tonti's diagram [16]:…”
