This is generally necessary to enter some personal information such as age, height can be used, otherwise the data does not make sense! Body fat scales are used for reference,
Can be used to assess the state of the body,
but can not be used for medical purposes! Body fat scales are weighing scales that can measure fat, water, etc. in addition to weight. There are ito membrane and electrode sheet two materials on the market sensor to measure body fat.
The principle of the body fat scale is muscle contains more blood and other water, can conduct electricity, and fat is not conductive. Because the body of the current channel conductor is muscle, from the current through the ease of knowing the weight of the muscle, which can be judged in the proportion of the body. It has been found that if a certain frequency of electrical signals through the body, the fat part of the muscle and other tissues of the body than the "impedance" value is higher. When a safe and specific frequency electrical signal is passed through the body, the electrical signal will change to a different degree depending on the "impedance" value of the body.
Principle: Muscle contains more blood and other water, can conduct electricity, and fat is not conductive. Because the channel conductor of the body's electric current is muscle, from the ease of passage of the electric current can know the weight of the muscle, from which we can judge, in the proportion of body weight, muscle less people with a higher proportion of fat.
Correct health concept: a healthy body, lies in the balance of body fat, excessive accumulation of fat on the body to produce harm, leading to a variety of diseases. Human fat is an important part of the human body and has important functions and roles in the body, such as providing energy, protecting internal organs, maintaining body temperature, assisting in the absorption of water-soluble vitamins, and participating in the body's metabolic activities. However, too much fat can affect human health, leading to diabetes, cardiovascular diseases, etc.. In addition, patients with obesity diseases and often face a fear of heat, affecting the shape of the body, easy to fatigue and other kinds of suffering. Therefore, doctors and experts recommend to control the body size within a certain range. With the improvement of people's living standards, health issues are becoming more and more important, which also promotes the development of the science of body composition measurement. The electronic fat scale, based on the above principle, utilizes the electrode pads on the surface of the scale body in contact with the user's legs to measure the body resistance (bio-impedance) through a certain safe current. Then, based on the input user data and the measured body resistance, using the formula we have obtained from extensive experiments, we can more accurately measure the percentage of body fat, the percentage of body water, the percentage of body muscle, the weight of bones and other body components.
