Study type: Medical/biological study (experimental study)

Magnetic field influence on electrical properties of human blood measured by impedance spectroscopy. med./bio.

Published in: Bioelectromagnetics 2005; 26 (7): 564-570

Aim of study (acc. to author)

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.

Background/further details

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.
