ABSTRACT:
Provided are a method and apparatus for measuring body fat using current electrodes and voltage electrodes. The method includes continually detecting a voltage drop across the voltage electrodes by smoothly raising a contact pressure applied to the electrodes; determining a threshold contact pressure with reference to the detected voltage drop depending on variation of the contact pressure, the voltage drop across the voltage electrodes not increasing under the threshold contact pressure even when the contact pressure increases; comparing a detected contact pressure with the threshold contact pressure; detecting a measurement voltage across the voltage electrodes only when the detected contact pressure is larger than the threshold contact pressure; and compensating the measurement voltage for a threshold contact voltage corresponding to the threshold contact pressure and calculating a body fat value corresponding to the compensated measurement voltage.
