    Abstract: A wrist-wearable body composition measuring device includes a main body; a strap connected to the main body; a first input electrode and a first output electrode which are provided on an inner surface of the strap and configured to contact a wrist of a subject; a second input electrode and a second output electrode which are provided on an outer surface of the strap; a measuring unit configured to measure a body impedance of the subject by applying current to the first input electrode and the second input electrode and detecting a voltage generated between the first output electrode and the second output electrode in response to the applied current; and a processor configured to analyze a body composition of the subject based on the body impedance measured by the measuring unit.

    Abstract: An apparatus for obtaining bio information includes: a first electrode portion including a current electrode and a voltage electrode arranged to contact a first body portion of a subject; a second electrode portion including a current electrode and a voltage electrode arranged to contact a second body portion of the subject; and a measuring unit configured to measure a bio impedance of the subject by applying a current to the current electrodes of the first and second electrode portions and detecting a voltage at the voltage electrodes of the first and second electrode portions. In order to decrease errors of a measured bio impedance, contact resistances of the first and second body portions of the subject contacting the current electrode and the first and second body portions of the subject contacting the voltage electrode are different from each other, for at least one of the first and second electrode portions.
