Description

Complex electronic weigher

The present invention relates to a composite electronic weight scale, and more specifically, to measure the body weight, height and human impedance of the user at the same time body fat, body fat versus height (BMI), basal metabolism, muscle mass, body moisture, visceral fat, protein rate, subcutaneous It makes it easier to measure body composition data such as fat and skeletal muscle mass, and also distinguishes between left and right body weight, displays left body weight, right body weight, and total body weight. The present invention relates to a composite electronic scale that can help to resolve the body imbalance by allowing the user to identify and recognize the body imbalance by displaying.

In the physical examination, the state of health of a subject has been confirmed using the height measured by a height meter and the weight measured by a weight scale as judgment conditions.

The scale has evolved into a digital scale using a load cell to supplement the precision of the analog scale that has been used for a long time.

On the other hand, as the average life span of humans has recently been extended and interest in health has increased, body fat, body mass index (BMI), basal metabolism (kcal), muscle mass, body moisture, visceral fat, protein rate, as well as height and weight As a judgment condition, the health status of the subject was confirmed.

To keep pace with this phenomenon, a metal pad is installed on the surface of the scale or a conductive film is coated on the entire surface to measure body weight, body fat, body mass ratio (BMI), basal metabolism, muscle mass, body water, visceral fat, A complex electronic scale has been developed to allow measurement of body information such as protein rate, subcutaneous fat and skeletal muscle mass.

In addition, the conventional composite electronic scales display the measured and calculated body information along with the measurement date and time on the mobile terminal in which the mobile application is installed through Bluetooth communication, and store the data in the body information DB. Information data is displayed by date, and changes in each physical information can be used to help health management.

On the other hand, people may live with body imbalances that are biased left or right due to their usual lifestyles and postures.These body imbalances are not easily identified by looking at the full-length mirror, so their bodies are imbalanced. You will not be aware that you are in one condition, and as this body imbalance continues, your health will be seriously affected.

This body imbalance can be confirmed by measuring the left body weight and the right body weight, but the conventional weight scale is to measure the body weight only, it is not able to distinguish the left body weight and the right body weight to determine the body imbalance yourself Can't.
