Description

Technical Field

[0001] The utility model relates to the technical field of body fat scales, in particular to an intelligent body fat scale based on high-precision sensor control. Background Art

[0002] Body fat refers to the weight of fat in the human body, which is generally expressed as body fat percentage, that is, the percentage of fat weight in the human body to the total weight of the human body. It is an important criterion for measuring whether a person is obese. Body fat scales can not only measure a person's weight, but also body fat. The main principle is to pass a weak current through the human body and use the difference in resistance between fat and muscle to current conduction to measure body fat percentage. When current passes through, the muscle part produces a smaller resistance, while the fat part produces a larger resistance. By analyzing the difficulty of current passing through the body, the proportion of fat and muscle in the body can be calculated, thereby obtaining the body fat percentage.

[0003] When using a body fat scale, a person's feet need to stand on the panel of the body fat scale and apply pressure to the sensor through the bottom of the panel to measure the body weight and body fat. The sensor is prone to distortion and displacement after repeated pressure, which affects the measurement accuracy. Therefore, an intelligent body fat scale based on high-precision sensor control is needed. Utility Model Content
