On evaluation of electric conductivity by mean of non equilibrium thermodynamic approach with internal variables. An application to human erythrocyte suspension for metabolic characterizations

In this paper we will approach a new method to obtain electrical conductivity by means of dielectric measurements. After a remark on non-equilibrium thermodynamics with internal variables formulated by Kluitenberg, we introduce complex conductivity and the relationship with the complex dielectric constant. Taking into account the dielectric model by us introduced we determine the real and imaginary part of conductivity as function of the frequency of perturbation. Also we determine phenomenological and state coefficients that lead to the determination of the two components in which is splitted the polarization, and to the entropy production due to electrical conductivity. These results are applied to an human erythrocyte suspension for metabolic deductions.
