The impedance spectroscopy technique was used for studying the effect of a 0.5 Tesla magnetic field on the electrical properties of human blood. The aim of the study was to demonstrate the feasibility of using a physical measurement provided by impedance spectroscopy technique for hematology research, in particular to get information on how magnetic field influences the human blood.
Impedance spectroscopy technique has been commonly used to determine the electrical characteristics of a wide range of materials. The principle of this technique is based on the frequency response of the material when a harmonic voltage is applied.
