[Principle of Health Scale] A magic scale that can measure the health level.

I believe that most of my friends will have a health scale at home, which is our weighing scale. It can help us monitor our weight changes at home anytime and anywhere, and some new healthy weighing scale can even detect our fat content. So how many people know how this practical health scale works?

Health scales are different from our traditional mechanical scales. As long as we stand on them, we can get our current weight quickly. Health scales are also divided into mechanical and electronic. As all friends who have used it know, a big defect of mechanical health scale is that the pointer will deviate, which leads to inaccurate measurement, and we need to adjust it frequently to ensure the accuracy of the pointer. Electronic health scales will not have this problem. As long as there is enough electricity, the electronic health scale can accurately measure our real-time weight.

Mechanical health scale is essentially the deformation of a balancer. When we stand on the mechanical health scale, we will exert a pressure on the health scale, which will cause the scale face of the mechanical health scale to move downwards. This displacement will be converted into the pointer deflection angle of the data display area of our mechanical health scale through the pre-designed measurement standard and a series of devices inside the mechanical health scale. The greater our weight, the greater the pointer deflection angle, so that we can get our weight according to the pointer deflection angle and the relative scale of the pointer.

The electronic health scale has many pressure sensing points evenly distributed on the scale surface. When we stand on the electronic health scale, these pressure sensing points can receive the pressure values taken when we stand on the scale surface, and then transmit these data to the built-in chip in the electronic health scale through electrical signals. After a series of calculations, the chip will get our weight value, and finally our weight value will be fed back to us in the form of Arabic numerals through the LED screen on the scale surface.

Now there are some new electronic health scales on the market that can measure fat content, and the principle is very simple. Because all kinds of tissues in the human body contain certain moisture or other electrolytes, they all have different conductivity more or less, while adipose tissue is not easy to conduct electricity without moisture. The new electronic health scale uses this feature to calculate the fat content in the human body.

It should be noted that, in fact, there are many brands or counterfeit businesses on the market now, which produce health scales with poor quality and accuracy in order to make profits. Therefore, in order to accurately monitor their weight changes and body data, I still suggest that you buy products with a certain reputation brand in regular shops or shopping malls.
