Abstract

Method for Controlling Electrodes for Bio impedance Measurements and Apparatus for Bio impedance Measurements There is provided a control circuit for electrodes in a bio impedance measurement system the bio impedance measurement system comprising screening current injecting electrodes and measuring current injecting electrodes the control circuit comprising: a current generator for connection to at least one screening current injecting electrode; and an measuring signal output configured to establish a measuring potential between the measuring current injecting electrodes wherein the control circuit is configured such that the measuring potential is dependent on a measure of a potential difference resulting from the screening current. The control circuit uses the value of the potential resulting from the screening current to determine the potential difference between the measuring current injecting electrodes. In this way the flow of measuring current can be made smaller than the screening current and necessarily at a safe level.
