Another intelligent function of the intelligent body fat scale is to measure body fat, moisture, muscle and many other functions. Why is it so powerful? In fact, the internal hardware has only another function.

The weighing surface of the smart body fat scale is composed of four electrodes, and their function is to measure the impedance of the human body. Since the APP supporting the ordinary smart scale requires us to input information such as gender, age, height, etc., the data of various components of the human body can be calculated through formulas.

There is impedance in the human body. In order to measure the impedance of each part of the human body, the human body can be divided into 5 segments: left upper limb, right upper limb, trunk, left lower limb and right lower limb.

The sinusoidal current source generated by the signal generating circuit is used as the excitation signal of the system and applied to the corresponding parts of the human body through the electrodes. A more accurate approach is to use an eight-electrode (4 pairs) measurement system, each pair includes an excitation electrode and a detection electrode.

But the 8-electrode weighing is obviously inappropriate. Smart scales should be more convenient. Therefore, all scales on the market are measured by the four-electrode method. The four electrodes on the smart scale we have seen are two of them are excitation electrodes used to generate excitation signals. The other two are detection electrodes used to measure voltage. A sinusoidal excitation signal is generated by the excitation electrode, which is applied to the two feet of the human body, and then the other two electrodes collect voltage on the two feet respectively. Strictly speaking, this measurement is not the entire impedance of the human body, but it does not matter. , The later algorithm always has a way to fit the data of various components of the human body through the measured impedance.

The above is the principle developed by the smart body fat scale program. According to the principle that the body fat current is not conductive, but the muscle is conductive, the electrical impedance value is obtained, and then the electrical impedance value is combined with the height and weight data to calculate the body fat rate. But because it is calculated, sometimes different products may have some defects more or less, which need to be accurately marked, test records need to be made every day, and fixed points are fixed regularly.

Smart body fat scale redefines the way of health and is one of the entry-level opportunities for family health management. Tuya Smart has launched a new smart body fat scale solution for ordinary body fat scale manufacturers or traditional weight scale manufacturers who want to transform. It can help ordinary body fat scales and weight scales to quickly connect to the App, and users can view their body in real time through their mobile phones. It can be linked to other health equipment in the family, such as sleep monitors, smart bracelets, etc., to help users establish family health files in an all-round way.

This solution can meet the intelligent needs of various types of body fat scales, and can be widely used in family scenarios to help family members monitor various data indicators of the body, even if the mobile phone is not around, it will not hinder data storage. It can also be combined with SaaS-level applications in industries such as fitness, medical treatment and health insurance to provide differentiated services based on different user physical data to create a health care ecosystem.
