True hAPPiness APP provides macro-measured data of human body 17, Bluetooth app measures data of human body fat rate, water rate, metabolic rate, etc., exercise diet calorie intake suggestion (white), purchase macro-measured data of human body 17, and intelligent fat scale.

Body fat scale is a weighing instrument that can measure fat, moisture and so on besides weight. There are two kinds of sensors for measuring body fat in the market: ito film and electrode sheet.

The principle of human body fat scale is that muscle contains more water such as blood and can conduct electricity, while fat is not. Because the channel conductor of current in the body is muscle, the weight of muscle can be known from the difficulty of current passing, so as to judge the proportion of muscle in the weight.

According to the above principle, the electronic body fat scale uses the electrode on the surface of the body fat scale to contact the user's leg, and measures the human body resistance through a certain safe current. Then, based on the input user data and the measured human body resistance.

Using the formulas obtained from a large number of our experiments, we can accurately measure body components, such as body fat percentage, body moisture percentage, body muscle percentage and bone weight.
