Measurement device for measuring a bio-impedance and/or a bio-potential of a human or animal body and adapted to be worn on the body, including: at least two electrode sensors. Each of the at least two electrode sensors includes a first electrical contact configured to be in electrical contact with the skin of the body when the system is worn, and a second electrical contact. A single electrical connector electrically connects the at least two electrode sensors with each other via the second electrical contact. An active device is configured to cooperate with a subset of the at least two electrode sensors such that the potential of the electrical connector is substantially equal to a projected potential determined from the potential of the first electrical contact of each electrode sensor of the subset when the measurement device is worn.
