Abstract:
In the tissue impedance spectroscopy measurements ,four-electrode method are normally used. A measurement error caused by stray capacitance between lines of drive electrode and receive electrode is not a trivial problem. This paper studied this error and reached the results This stray capacitance introduces errors which increase with frequency and has more effect on the imaginary part than on the real part in the measurement frequency range.
