In this research we employ conductive properties of tumor cell, to develop a non-invasive hyperthermia systems. Here we use electrolyte-electrode polarization method to measure impedance, and to detect variation in ion concentration and different pH values. In the experiment, to effect of the following factors: (1) electrode geometry (2) estimation current by different resistance(3)different kind of ions (4) changed temperature (5)enhanced number of hydrogen ions and voltage. The experiment indicates that, when enhance number of hydrogen ions and voltage, notable difference in conductivity and temperature were obsrrved. In the future, we can apply the finding in hyperthermia thermal systems, it may destroy tumor cell''s and reduce injury the surrounding tissue
