The working principle of the body fat detector 100 provided by the embodiment of the application is as follows:

the opaque body fat detection electrodes 120 and the light-permeable panel 110 are distributed in a staggered manner to form a gradient pattern, and the gradient pattern is uniformly divided into four regions of the body fat detection electrodes 120 by the light-permeable region, so that a user can measure body fat by standing on a body fat detector.

Specifically, the user may step on the left area of the shielding cover 210 of the light-permeable panel 110 shown in fig. 2 with the left foot in a barefoot state, and may step on the right area of the shielding cover 210 of the light-permeable panel 110 with the right foot, thereby forming an energizing loop that shields the shielding cover 210 from the left body fat detection electrode 120-the left foot of the user-the body of the user-the right foot of the user-the body fat detection electrode 120 on the right side of the shielding cover 210. The control circuit board 150 is electrically connected to the four-piece fat detection electrodes 120, respectively, and the control circuit board 150 measures and calculates the body fat, muscle, moisture and bone percentage of the user using a Bioelectrical Impedance Analysis (BIA for short) and basic parameters of the user, such as height, weight, sex, etc.

The principle of bioelectrical impedance analysis is that when weak AC current signal is led into human body, the current will move with small resistance and good conductivity. The amount of moisture determines the conductivity of the current path, which can be expressed by the measured value of impedance, and the moisture content of fat and muscle in the human body are different, so that the body fat of the user can be measured by BIA according to the difference between the moisture contents of fat and muscle in the human body.

The gradual change pattern ensures that the distribution area of the body fat detection electrode 120 is larger, and simultaneously, the integral integrity of the body fat detection electrode 120 and the light-permeable panel 110 is stronger, and the split feeling between the body fat detection electrode 120 and the light-permeable panel 110 on the light-permeable panel 110 is reduced, when the display screen 130 is not lighted, the light-permeable panel 110 of the body fat detector is shown in fig. 2, when the display screen 130 is lighted, the information of the display screen 130 can be presented at the position I in fig. 2, the L ED dot matrix display screen 130 can be better matched with the light-permeable area in the circular shape, so that the information display of the display screen 130 is clearer, and the display screen 130 is connected with the control circuit board 150, and can receive the high level signal and the low level signal transmitted by the control circuit board 150, so as to display the information.

The pressure sensor 160 may measure the weight of the user while the user stands on the body fat detector. The PPG sensor 170 is used to measure physiological characteristics of a user, and since the physiological characteristics of different users are different, the currently measured user can be distinguished according to the difference of the physiological characteristics, so that the body fat detector 100 can measure body fat of a plurality of users, and the body fat detector 100 can automatically distinguish identities of the plurality of users according to the physiological characteristics acquired by the PPG sensor 170.

Specifically, the light emitter of the PPG sensor 170 is configured to emit light through the light-permeable panel 110, the light detector is configured to receive light reflected back from the human body, the light is emitted to the skin, the light reflected back through the skin tissue is received by the light detector, and the PPG sensor 170 may transmit both the light emitted by the light emitter and the light received by the light detector to the control circuit board 150, and the light is processed and analyzed by the control circuit board 150 to obtain the physiological characteristics of the user.

The support plate 180 is arranged in the hollow accommodating cavity, the support plate 180 can support the body fat detector 100, and meanwhile, the positions of the pressure sensor 160, the display screen 130 and the PPG sensor 170 can be fixed, so that the pressure sensor 160 and the PPG sensor 170 can accurately perform measurement actions at respective positions, and the display screen 130 can clearly display measured values at the fixed positions.
