Can be used to evaluate physical condition,
But it cannot be used for medical treatment! Body fat scale is a weighing instrument that can measure fat, moisture and so on besides weight. There are two kinds of sensors for measuring body fat in the market: ito film and electrode sheet.
The principle of human body fat scale is that muscle contains more water such as blood and can conduct electricity, while fat is not. Because the channel conductor of current in the body is muscle, the weight of muscle can be known from the difficulty of current passing, so the proportion in the body can be judged. It is found that when an electrical signal with a certain frequency passes through the human body, the "impedance value" of the fat part is higher than that of muscles and other tissues of the human body. When an electrical signal with a safe specific frequency passes through the human body, the electrical signal will change in different degrees due to the different "impedance values" of the human body.
Principle: Muscle contains more water such as blood, which can conduct electricity, but fat can't. Because the channel conductor of current in the body is muscle, the weight of muscle can be known from the difficulty of current passing, so it can be judged that people with less muscle have a higher proportion of fat.
Correct health concept: A healthy body lies in the balance of body fat. Too much fat accumulation is harmful to the body, leading to various diseases. Human fat is an important part of the human body, which has important functions and functions in the human body, such as providing energy, protecting internal organs, maintaining body temperature, assisting the absorption of water-soluble vitamins, and participating in human metabolic activities. However, too much fat will affect human health, leading to diabetes, cardiovascular and cerebrovascular diseases. In addition, obese patients often face various troubles such as fear of heat, influence on body shape and fatigue. Therefore, doctors and experts suggest keeping your body shape within a certain range. With the improvement of people's living standards, health problems are paid more and more attention, which also promotes the development of human body composition measurement science. According to the above principle, the electronic fat scale uses the electrode pads on the surface of the scale to contact the user's legs, and measures the biological impedance through a certain safe current. Then, based on the input user data and the measured human body resistance, we can accurately measure human body components, such as body fat percentage, body moisture percentage, body muscle percentage, bone weight and so on, by using the formulas we have obtained in a large number of experiments.
