Electrical conductivity of tissue at frequencies below 1 MHz

TLDR

The study combines a literature review of the past decade with in vivo pig tissue measurements and in vitro pig fluid experiments to characterize tissue conductivity below 1 MHz. Conductivity values were obtained for skeletal and myocardial muscle, liver, skull, fat, lung, and various body fluids, and a critical analysis of these data highlights their strengths, limitations, and recommendations for future measurements.

Abstract

A two-pronged approach, review and measurement, has been adopted to characterize the conductivity of tissues at frequencies below 1 MHz. The review covers data published in the last decade and earlier data not included in recent reviews. The measurements were carried out on pig tissue, in vivo, and pig body fluids in vitro. Conductivity data have been obtained for skeletal and myocardial muscle, liver, skull, fat, lung and body fluids (blood, bile, CSF and urine). A critical analysis of the data highlights their usefulness and limitations and enables suggestions to be made for measuring the electrical properties of tissues.
