Abstract	The dielectric properties of red blood cell suspension (RBCs) samples with different packed cell volume (PCV) values were measured by using Novocontrol's Concept 80 Broadband Dielectric Spectrometer of 1 Hz to 1 GHz at temperature ranging from 0°C to 42 °C. There are two relaxation processes on the dielectric spectrum of RBCs samples; one is related to the ions accumulated on double layer boundary of cells and the other to Maxwell-Wagner interface polarization. It was observed that along with the rise of temperature, the peak of dielectric loss moved to high-frequency area and the RBCs sample with higher PCV value got a lower peak. With characteristic relaxation time at various temperatures, RBCs relaxation activation energy and the relative permittivity of cellular membrane were calculated as being close to the known value of $phospholipids.^{1}$
