Abstract :
Impedance measurements are being used as a noninvasive method for evaluation of tissue characteristics. However, the challenge is that there is no known unique correlation between the electrical behavior of tissues and their physiological parameters. The purpose of this research is to establish the groundwork that would lead to this correlation, by investigating the electrical properties of biological tissue. Experimental measurements were conducted on excised canine muscle samples using PC controlled instrumentation. The resistivity of the skeletal muscle was measured at various frequencies, angles between the fiber orientation and electrode axis, and sample thicknesses
