How does an electronic scale measure fat? What is the principle of an electronic fat scale?

In detail, there should be an ITO conductive film on the surface of the fat scale, and the weak bioelectricity circulating in the body without damage is measured by the BIA (bioelectrical impedance analysis) method. Here's how it works: Since body fat conducts little electricity, while body components such as muscle and water do, they do, so a fat scale can calculate the ratio of body fat, water, and other tissue components by measuring the body's bioelectrical impedance.

This is different from the general electronic scale, which only calculates the fat percentage based on height, waist circumference, weight, etc. BIA's approach is more precise. When a specific frequency electrical signal passes through the human body, it conducts electricity because the muscle contains more water such as blood, while fat does not.

As a result, resistance can be calculated and body components such as fat, muscle, and bone weight percentages can be accurately measured using scientific formulas. In fact, common parameters such as body fat percentage, water, muscle, and bone mass are actually "calculated". For example, the fat content needs to be calculated according to the formula for weight, gender, age, and height, in which the weight is obtained by measurement, and the gender, age, and height need to be entered by the user himself.

The measurement principle of the body fat scale, known as the BIA bioelectrical impedance measurement method in the industry, is the general measurement method of almost all body fat scales, body composition meters and other measurement tools on the market, the specific principle is that the scale body emits a weak current through the electrode sheet, forming a closed loop with the human body, through the principle that the muscle is easy to conduct electricity, and the fat does not conduct electricity, an electrical impedance value is obtained, and then the electrical impedance value is combined with height, weight and other data to calculate the body fat rate. Many people think that the body fat scale is deceiving, and a lot of data is calculated by calculation, but in fact, with the current body fat measurement technology in the world, it is very cumbersome and difficult to measure the body data accurately, which is also the main reason why most of the industry uses the BIA measurement method. In addition, the use scenario of the body fat scale is positioned at home, it weighs anytime and anywhere, and the convenience and accuracy of obtaining data are very high.

The body fat scale is a weighing meter that can measure fat and moisture in addition to body weight, and there are sensors on the market that measure body fat with two materials: ITO membrane and electrode sheet.

The principle of the human fat scale is that muscle contains more water such as blood and can conduct electricity, while fat does not conduct electricity. Because the conductor of the current in the body is the muscle, the weight of the muscle can be known from the ease with which the current is crept through, and the proportion in the body can be determined.

Studies have found that when a certain frequency of electrical signals passes through the body, the fat part has a higher "impedance" value than the muscle and other tissues of the body. When a safe electrical signal of a specific frequency passes through the human body, the electrical signal will change to varying degrees depending on the value of the "impedance" of the human body.

Principle: Muscle contains more water such as blood and can conduct electricity, while fat does not. Because the channel conductor of the current in the body is the muscle, the weight of the muscle can be known from the difficulty of the current passing, and it can be judged that the proportion of fat in people with less muscle is higher in the proportion of body weight.

Correct health concept: a healthy body lies in the balance of fat in the body, and excessive fat accumulation is harmful to the body and leads to various diseases. Body fat is an important part of the human body, and it has important functions and roles in the human body, such as providing energy, protecting internal organs, maintaining body temperature, assisting in the absorption of water-soluble vitamins, and participating in human metabolic activities.

However, excessive fat can affect human health, leading to diabetes, cardiovascular and cerebrovascular diseases, etc. In addition, patients with obesity often face various troubles such as heat intolerance, affecting body shape, and fatigue. Therefore, doctors and experts recommend keeping your body shape 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 measuring body composition.

According to the above principle, the electronic fat scale uses the electrodes on the surface of the scale body to contact with the user's legs, and measures the human body resistance (bio-impedance) through a certain safety current. Then, based on the input user data and the measured body resistance, using the formulas obtained in our extensive experiments, we can accurately measure body components such as body fat percentage, body water percentage, human muscle percentage, bone weight, etc.

Since the channel conductor of the current in the body is the muscle, the weight of the muscle can be known from the difficulty of the current passing, and it can be judged that the proportion of body weight is higher in people with less muscle.
