Method and apparatus for measuring local body fat by using bioelectrical impedance technology

摘要

A method and apparatus for measuring local body fat using the bioelectrical impedance analysis where a flat bottom plane of the impedance-measuring apparatus has four electrodes to connect to a pre-selected segment of the body to measure the body fat content, which allows all four electrodes on the bottom plane to be connected to the human body at the same time. When the impedance-measuring apparatus is connected to the person tested, a weak current is sent through the current electrodes and the body tissue. Since the resistance characteristics of body fat mass and fat free mass is quite different, the resistance values measured from segments of the body can provide useful information for computation of the proportion of fat free mass and body fat mass in the body.
