Dielectric Spectroscopy Applied to Porcine Tissues

Abstract

This paper discusses the characteristics of the dielectric properties: permittivity (E), conductivity (ó) and dielectric loss (E") of a porcine tissue. The main objective is to measure and identify the dielectric properties of a porcine lung tissue and porcine cardiac muscle tissue in the frequency range of 20Hz-20MHz. The sample of the lung tissue (0.88 mm2) was extracted from a pig fetus and the cardiac muscle tissue (2.10 mm2) from an adult pig. The previously preserved and vacuum sealed organs were stored at 15ºC. Afterward, the sample tissues were placed in individual bags and stored in a portable cooler until the electrical parameters were measured. The dielectric properties were calculated and measured by the Impedance Analyzer E4990 A and the Dielectric Material Test Fixture model 16451B. Both tissues properties were analyzed. The results agreed with literature.
