The water content of human body is about 70%, mostly in blood, lean meat and internal organs, while the water content in fat is extremely low. Water in the body shows low resistance due to the dissolution of various components, while fat shows high resistance, so the ratio of fat to water in the human body affects the resistance of the human body. If the synthetic resistance of fat and water is considered, the human body with more fat has higher resistance.
Muscle, water and other body components are easy to conduct electricity, so the body fat detector can calculate the proportion of body fat, water and other tissue components by measuring the bioelectrical impedance of the human body.
There is ITO conductive film on the surface of the fat measuring instrument, and there is no damage and weak bioelectric cycle in the body, which is measured by BIA. First, apply a weak current to the human body, and then judge the body fat rate according to the current impedance. The current flowing through the human body is very weak (50KHz, 500uA), so there is no feeling of stimulation, which is very safe for the human body.
