Theoretical Analysis of Switching Tetrapolar Electrode Array for Bioimpedance Measurements

This work presents a theoretical framework for using switching tetrapolar electrode arrays in the bioimpedance studies. Changing the current injecting and voltage measuring electrode pairs in the array of 4 electrodes gives enough electrical impedance measurement data of an object to reconstruct properties of its inner structure. This technique will be useful for some medical bioimpedance measurements, as it allows to gather more information quickly and without the reapplication of the electrode array.
