Gelatin as a skin phantom for bioimpedance spectroscopy

Abstract

A phantom is an object that mimics living tissues. In this manuscript, the preliminary results of gelatin’s characterization as a skin phantom for electrical impedance spectroscopy are presented. Skin and gelatin’s impedance modulus characteristic spectra are measured. Similarities between the impedance modulus spectra of skin and gelatin were found for different skin sites, showing that gelatin can be used as a skin phantom in electrical impedance spectroscopy, due to its spectral characteristics and flexibility of design.
