Description

Skin moisture and body composition measurement system and its device {SYSTEM FOR MEASURING SKIN MOISTURE AND BODY COMPOSITION AND APPARATUS THEREOF}

Embodiments of the present invention relate to skin moisture and body composition measurement techniques.

Components constituting the human body can be largely divided into water, protein, bone (mineral) and fat, and quantitatively measuring these components is called body composition analysis. Body composition analysis is widely used as a test that provides the most basic and essential information to check the health status of a subject, and is effective in discriminating diseases and symptoms such as obesity, osteoporosis, malnutrition, and edema. In the case of modern people, obesity-related diseases such as adult diseases are on the rise due to busy daily life and western eating habits.By analyzing body composition, it is important to accurately diagnose obesity by presenting the proportion of body fat in body weight and to treat it. Is utilized.

Various methods such as underwater density method, sebaceous method, and near-infrared method are used for the analysis of body composition, but the most widely used method is a bioelectrical impedance method (BIA). The bioelectrical impedance method is a method in which weak alternating current is flowed into the human body to measure the electrical impedance or electrical conductivity of the human body to calculate water content in the body, water balance in and out of the cell, and body fat.

Meanwhile, the skin corresponds to a human skin, and has functions such as human body protection, body temperature control, excretion and breathing. The function of the skin depends on the skin condition, especially the amount of moisture contained in the skin.

The bioelectrical impedance method (BIA) is the most widely used method for measuring moisture in the skin.

However, the conventional body composition measuring device and skin measuring device provided for measuring body composition and skin moisture using a bioelectrical impedance analysis (BIA) have the advantage of being able to measure body composition and skin anywhere in a portable environment. , As the devices for body composition measurement and skin measurement are implemented as separate devices, a body composition measurement device and a skin measurement device must be provided separately, and a user may use a body composition measurement device and a skin measurement device to measure body composition or measure skin. Since it must be carried separately, there is a problem that portability is lowered.
