AC impedance measurement of the dielectric spectra for normal human blood cells / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To study the data characteristics of dielectric properties of normal blood cells.</p><p><b>METHODS</b>The AC impedances of blood samples from the 30 healthy volunteers were measured with impedance analyzer at the radio frequency range, and its frequency properties were assess in view of the dielectric spectroscopy, complex plots, loss factor, imaginary part of conductivity and loss tangent.</p><p><b>RESULTS</b>The permittivity and conductivity of healthy adult whole blood cells had a dependence of frequency. The dielectric properties of human blood cells had two characteristic frequencies at 0.59 MHz and 2.12 MHz.</p><p><b>CONCLUSION</b>The frequency properties of blood cells can be obtained by impedance analysis within the frequency range.</p>
