US Patent 7130680 Body composition measurement apparatus

Disclosed is a body composition measurement apparatus, comprising: a current supplying unit; a voltage measurement unit; a bioelectrical impedance measurement unit; and a judgment unit. According to the present invention said current supplying unit supplies an electric current to a person under test, said voltage measurement unit measures an electric voltage, and said bioelectrical impedance measurement unit measures a parameter for bioelectrical impedance of a measured part of the person, based on the current supplied and the voltage measured. Furthermore, said judgment unit judges an index for cell age of the person, based on the measured parameter for bioelectrical impedance.
