[The experimental research for dielectric spectroscopy of human blood cells]

The dielectric spectroscopy of human blood cells was measured within the frequency range of 0.01-100 MHz, and the dielectric numerical characters were determined as response to AC electric field. we measured the AC impedance of normal human blood cells with the impedance technique in the frequency domain, then the experimental data were drawn a relationship curve between the frequency of electric field and conductivity. The dielectric spectrum and the Cole-Cole plots of human blood cells were established. The characteristics of dielectric response of human blood cells were also established. The permittivity and the conductivity of human blood cells were frequency dependent, and dielectric dispersion of human blood cells had two characteristic frequencies: i.e. fc1, is 1.42 MHz, and fc2 is 3. 32 MHz.
