The working principle of smart body fat scale

The body fat scale uses the bioelectrical impedance method, because the human body is composed of two components: adipose tissue and non-fat tissue. Different components in the human body have different electrical impedance. The size of electrical impedance is determined by the amount of water content. Fatty substances have low water content, large electrical impedance, poor electrical conductivity, but high content of fatty substances, low electrical impedance, and good electrical conductivity.

There are several electrode pads on the surface of the smart body fat scale. When a person stands barefoot on the body fat scale, the electrode pads introduce a certain frequency of current to the human body (don’t worry, it’s static electricity), and then combine certain parameters of the body with the measured resistance Resistant, can calculate the volume of non-fat substances in the human body, obtain the content of non-fat substances in the human body, and then calculate the content of human fat substances and calculate the body composition. Because this method is simple, convenient and time-consuming, it is currently the most common method of use.
