Dielectric characterization of permittivity, conductivity and loss factors of porcine tissues by impedance spectroscopy

Abstract

This investigation was performed to determine whether the mean of fetal porcine tissues analyzed by impedance spectroscopy for their properties adhered to the idealized plots The statistical process was with the purpose of finding a correlation that established the values as normal and true For this study 2 samples of 3 types of tissues were obtained, a bone, muscle, and skin sample All samples belonged to a pig fetus, preserved in formaldehyde an unknown number of days The parameters were measured with an Impedance Analyzer with a Dielectric Test Fixture at a frequency range of 20 Hz to 20 MHz In total, 5 tests were performed per sample per tissue To comply with the statistical approach taken for this investigation, the standard of these 5 tests was calculated for each of them Higher beta elevations were observed in all conductivity plots along with a sharp decrease affecting beta in all the permittivities It’s proposed that this is just the normal electrical behavior of fetus samples Though similar, these fetus tissue samples did not adhere to the idealized plots they were meant to follow, which meant the hypothesis was not supported
