The Fat Gauge utilizes the principle of fat non-conductivity to measure body resistance through a weak electric current flowing through the hands and feet, thus determining body fat percentage.
The water content of the human body is about 70%, and the vast majority of this water is found in blood, lean meat and internal organs, while the water content of fat is extremely low. The body water due to the dissolution of a variety of components and presents a low resistance, but the fat presents a high resistance, and thus the proportion of fat and water in the human body affects the resistance of the human body, if you consider the synthesis of the resistance of the fat and water, the body with more fat resistance value is high.
While body components such as muscle and water are easy to conduct electricity, so the body fat detector can calculate the ratio of fat, water and other tissue components in the body by measuring the bioelectrical impedance of the body.
The fat meter has an ITO conductive film on its surface, and non-destructive weak bioelectricity circulates through the body, measured by BIA. A weak electric current is first passed through the body, and then the body fat percentage is judged based on the current impedance situation. The current flowing through the body is very weak (50KHz, 500uA), so there is no sensation of irritation and it is very safe for the human body.
