Abstract
A system for measuring electrical impedance particularly of biological tissues to provide an indication of the condition of such tissue. The system comprises a source of constant-amplitude current and three pairs of electrodes, of which the first pair constitutes excitational electrodes, the second pair constitutes sensing electrodes, and the third pair constitutes focusing electrodes to focus the current flowing between the two excitation electrodes to the region occupied by the sensing electrodes. The system further includes synchronized switching means for alternately connecting the first group and the second group of electrodes to the excitation source.
