On evaluation of electric conductivity by mean of a thermodynamical model for dieletric relaxation phenomena. An application to liver tissue

Vincenzo Ciancio, Francesco Farsaci


In this paper we study the electric conductivity of continuous media in the contest of the non-equilibrium thermodynamics with internal variables. Namely, we shall use some recent results that allow to infer conductivity as function of the frequency of perturbation, only by means of dielectric measurements. Although the results obtained can be applied to several materials, we have applied them to the study of electric conductivity on porcine liver tissue obtaining the spectrum frequency of conductivity (real and imaginary part).
