Permittivity of blood
WebFor these reasons many models of the permittivity of blood (or similar materials) have been proposed in the literature, fitting Debye or Cole–Cole models to experimental measurements [6,7,8,9,10,19,20].The studies differ in the materials used (human blood, animal blood, plasma, and water/glucose solutions), frequency ranges, glucose concentrations, and … WebEDTA (0.2 ml) and the blood sample used presents an haematocrit of 45%. The volumes of anticoagulant used do not modify the dielectric value of blood. A comparative study of the dielectric parameters of pure human blood and human blood with EDTA and heparin show that there are no significant divergences. The results have been presented in more ...
