Abstract
Comparative study of dielectric properties of the skin of human and laboratory animals
Highlights
The skin, despite the superficial localization, being a difficult object for visualization, for a long time remained only the subject of histological examination [2, 5, 7, 9,10,11,12]
The linear regression equation, which allows to predict the value of dielectric permittivity at other sensing depths, is presented in the following form: y 6,4125 x 15,844 (1)
Analysis of the dielectric properties of rat skin allowed to establish that the permeability of the latter is significantly, almost an order of magnitude lower than in humans, but the nature of the dependence of the considered parameter remains, demonstrating a monotonously increase in the value with a maximum at a depth of 5 mm
Summary
The skin, despite the superficial localization, being a difficult object for visualization, for a long time remained only the subject of histological examination [2, 5, 7, 9,10,11,12]. A more extensive methodological apparatus is available for monitoring skin vessels [5], while the deep structure of the latter is difficult for non-invasive study [1, 2, 5] In this regard, the work on profiling of the skin by its dielectric properties attracts attention [1, 3, 4, 6, 8], but this information is isolated and jerky. The work on profiling of the skin by its dielectric properties attracts attention [1, 3, 4, 6, 8], but this information is isolated and jerky This is, in particular, due to the lack of available diagnostic tools for assessing the dielectric characteristics of the skin and other tissues [3, 4]. The aim of the study was to study the possibilities of near-field microwave sensing in assessing the structure of human and rat skin
