What is a smart scale? Benefits and principles of operation

Smart scales are becoming more and more popular in every home, making it more convenient and accurate to control health indicators. Let’s find out more specifically what a smart scale is, its benefits and operating principles, through this article!

What is a smart scale?

Smart scale is an electronic health scale that helps manage weight and other parameters such as: Body mass index, fat, body water, muscle mass, body water percentage, mass bone, protein ratio, body age,…

In addition, the scale also has the ability to remember body parameters, helping users to control nutrition and physique every day. Thanks to this type of scale, you can be more proactive in adjusting your exercise regimen and proactively protecting your health .

Structure of smart scales

Structure

Smart scales are made up of many parts, but mainly include the following components:

• Weighing plate : Also known as the weighing platform, manufactured by stainless steel, plastic, … used to place the object to be weighed or the foot on the scale.
• Load cell : When a heavy object is pressed on the weighing plate, this part is responsible for transmitting electrical signals to the board of the scale.
• Amplifier circuit : Because the electromagnetic signal from the loadcell is too small (mV rows), it is necessary to have this part to amplify that signal larger, helping to avoid errors when measuring and processing signals. than.
• Signal converter circuit and microprocessor : The microprocessor is capable of processing digital signals, while the signal converter circuit is responsible for converting the signal from the loadcell to transmit after amplifying the electrical signal to the signal. This circuit is also known as the A/D circuit.
• Indicators and interactive keys : It is responsible for helping the screen display the measured value and function keys to fulfill the user’s request.

Working principle

When standing on the scale, the loadcell will be bent due to the weight of the body weight. At the same time, the metal rod will be bent, causing the resistor to stretch and change the resistance parameter.

Depending on the mass of the object, the Loadcell will be bent by a corresponding amount. This amount will be measured by the change in resistance.

Pros and cons of smart scales

• Weighing body weight
• Set up different modes of the scale to monitor your weight and health status every day.

Body fat can only be approximated and they may affect the accuracy of the scale. Specifically due to the following factors:

• Gender : Women generally have more body fat than men.
• Pregnancy : It is difficult for the scale to give an accurate reading when you are pregnant.
• Age : Some scales are not suitable or accurate for children.
• Your height and stature .
• Status: People who regularly undergo and practice heavy exercises will have different stats than people with the same body mass but who do not practice the same exercises.

In addition to weight, smart scales can measure the following metrics:

• Body fat percentage : The ratio of fat to your overall weight. Body fat percentage is calculated by a formula that includes 5 factors: electrical impedance, height, weight, age and gender.
• Total Body Water : This is a percentage of total body fluid relative to body mass.
• Body mass index of a person BMI: Calculated by the person’s weight (kg) divided by the square of height (m).
• Muscle Mass : Muscle mass includes the mass of skeletal muscle, smooth muscle such as heart muscle, digestive system muscle, and water contained in muscle cells.
• Body mass index : This feature classifies a user’s physique based on his/her body fat percentage and muscle mass.
• Visceral fat index : The index shows the amount of fat in the abdominal cavity, surrounding the internal organs.
• Basal Metabolic Rate BMR: The minimum amount of energy (calories) a person needs in 24 hours at rest, ensuring the body’s functions work properly.

Notes when using smart electronic scales

In order to use the smart electronic scale accurately, safely and effectively, please immediately pocket the following usage notes:

• Do not suddenly drop or forcefully place the object to be weighed on the scale.
• Clean and wipe the scale after each use.
