Abstract
A portable body fat measurement apparatus using a near infrared ray, the apparatus including a near infrared sensor to receive a second near infrared ray reflected from a body part of a user after the body part is irradiated with a first near infrared ray, and to convert the second near infrared ray into an electrical signal, an alternating current signal extraction unit to extract an alternating current component from the electrical signal, and a body fat measurement control unit to compare an amplitude of the alternating current component with a predetermined threshold, and to generate an alarm signal when the amplitude of the alternating current component meets the threshold.
