In this study we focus on the validity of the skin layer currently implemented in up-to-date human-body anatomical models employed in low frequency (LF) numerical dosimetry. Indeed, the several layers of the skin structure, i.e. the stratum corneum (SC), dermis, and epidermis are in these models embedded into a unique fairly-thick (2-3 mm) layer encompassing all of them. While a previous work from the authors showed that for normal-standing (or limb-non-touching) postures a single-layer skin model could conservatively estimate the peak electric field induced in the skin, at least a two-layer skin model comprising of the SC and the remaining skin layers should be used for limb-touching exposure scenarios. This implies notable efforts to discretize the tiny SC layer questioning the validity of current anatomical models. A novel strategy based on the homogenization of the several skin layers has been therefore proposed in order to eliminate the SC from the computational domain opening the doors to future LF magnetic applications even for limb-touching scenarios.
