  • Title: Cell for measurements of biological tissue complex conductivity.
    Author: Wtorek J, Poliñski A, Stelter J, Nowakowski A.
    Journal: Technol Health Care; 1998 Sep; 6(2-3):177-93. PubMed ID: 9839863.
    Abstract:
    The construction of the cell for measurement of complex electric conductivity is described. Two-chamber and four-electrode system with temperature stabilisation is developed. Guarding chamber and electrodes are used to minimise the leakage of current from the measurement chamber. The cell construction is examined by use of Finite Element Method. The model of the measurement cell is examined in order to improve the accuracy of measurements. The calibration procedure based on measurement of reference materials is presented. The frequency range of the cell is extended to 10 MHz with acceptable level of error. The examples of results from measurement breast normal and cancerous tissues are presented.
