摘要：
Method for bio impedance measurement on a skin surface (1) of a living body, using a bio impedance measurement device comprising a sensing electrode (2) and a pilot electrode (9), comprising the following steps: - placing said sensing electrode (2) and pilot electrode (9) on the surface (1) of said body - providing a guard electrode (4) adapted to separate the surface (1) in at least two zones, among which a sensing zone including the sensing electrode (2) and a current injection zone including the pilot electrode (9) - providing a controller (27), electrically connected to said electrodes, adapted to control the current source (25) - controlling the potential of said guard electrode (4), at least at given stopping frequencies, in order to stop current from flowing from one zone to the other.
