The selling point of the Xiaomi Smart Scale is the BIA technology used in this product. It’ll be naive to think Xiaomi will come in with a well-designed product and nothing more. So you have to know this innovative technology is the main advantage of this scale in comparison to all other products from the same niche.
Briefly on BIA
The human body is composed of four main components – water, fat, protein, and minerals. Having a moderate amount of each component is important for a healthy life. BIA (Bioelectrical impedance analysis) is the most practical method to measure ration between them. For example, BIA sends electrical currents throughout the water in the body and measures the amount of resistance (aka impedance) as it travels. Therefore more water leads to lower impedance. Say, if two people have the same weight as well as the same height. But one of them has a higher amount of muscle mass than the second one. As muscle cells hold more water than fat cells, electrical currents can more easily flow through the first man’s body. Thus the impedance data will be lower. BIA can determine the volume of a person’s total body water.
However, since impedance is derived from factors such as length and area, different sizes would yield drastically different impedance values. So our body can be divided into five cylinders with different lengths and widths. Therefore, measurements should be segmentally analyzed. For example, trunk accounts for around 5% of the whole body impedance, but it’s responsible for about 50% of the whole body mass. So even a small change of 1-2ohms in the trunk impedance value can significantly alter the whole body lean mass.
Xiaomi Smart Scale Measuring Feature
Thanks to abovementioned technology the Xiaomi Smart Scale can measure a total of 10 human data concerning figure, weight, muscle mass, basic metabolism, bone mass, BMI, water, visceral fat level, body score, and fat rate. But this is Xiaomi. I mean we should require more from this technology.
Fortunately, Xiaomi has made some enhancements. Anytime you check out your weigh the data is recorded in your Mi app account. Therefore, you can get reports on how your weight has changed. But as the scale is not acquired for a single person only, Xiaomi has customized the software in the way to record up to 16 persons’ data.
At last, the Xiaomi Smart Scale comes with an ultra-thin design. So this technology doesn’t affect the thickness and we are dealing a well-looking product. There is also hidden LED displaying weighing results. The Smart Scale is priced only 199 yuan ($28.99).
