So, what is the "intelligence" of intelligent weighing scale?
1. working principle
In fact, the intelligent scale adopts bioelectrical impedance technology. Add ITO conductive film or conductive metal sheet to the surface of the scale. When the human body steps on it barefoot, a closed-loop electrode will be formed. Because fat is not conductive and water is conductive, the fat content in the body can be calculated by calculating the current value, resistance value and weight value. In other words, to measure the fat rate, you must walk barefoot.
Many gyms or hospitals have professional fat testers for testing. Their testing principle is actually the same, the difference lies in the number of electrodes. The more electrodes there are, the more detailed the parts that can be tested. Usually, the high-grade fat scales used at home are 4 electrodes, but there are also many cheap fat scales with 2 metal electrodes. Here is a simple way to judge the number of electrodes. If there are four metal test pieces or ITO conductive film on the scale, then the scale is four electrodes. If there are only two metal sheets or ITO conductive films on the scale, they are two electrodes, and the cost of ITO film is much higher than that of metal sheets.
2. Parameter meaning
The parameters of intelligent weighing scale include body weight, body fat rate, muscle rate, bone mass, basal metabolic rate, water content, body age and so on.
Weight: the weight measured naked or wearing work clothes of known weight.
Body fat rate: the proportion of body fat weight in the whole weight of human body, also known as body fat percentage, reflects the fat content of human body.
Muscle rate: Muscle rate is a proportional value of human body based on total muscle mass, weight and height. The range of this value determines a person's health and strength.
Bone mass: the content of bone tissue [bone minerals (calcium, phosphorus, etc. ) and bone matrix (collagen, protein, inorganic salts, etc. ) unit volume, used to indicate the health of bones.
Basal metabolic rate: the energy metabolic rate of the human body when it is awake and extremely quiet, which is not affected by muscle activity, environmental temperature, food and mental stress.
Moisture: refers to the water content in the body, including blood and body fluids.
Physiological age: also known as physiological age, refers to a person's physiological age. Is a brand-new concept, representing the vitality of this person. Physiological age mainly depends on people's lifestyle and health.
3. Cloud services
The most obvious difference between intelligent weighing scale and traditional weighing scale is that intelligent weighing scale can upload the tester's physical data to the cloud storage after the test, and even analyze the tester's health index through big data, so as to analyze the tester's physical health or guide his lifestyle.
Nowadays, smart weighing scale has its own mobile phone app, which has many functions, such as weight change record, slimming action guidance, exercise steps statistics and food calorie statistics, etc., all of which can be operated with one button on the mobile phone, which is very convenient.
Therefore, intelligent weighing scale is no longer just a concept of scale, it has become a health assistant in family life, a health manual for family members, and even a platform for sharing health with friends.
