1. Technological innovation: The embedded design of the eight-electrode body fat handle has a strong overall feeling, simple and elegant appearance. As a body fat scale, a safe electrical signal with a specific frequency passes through the human body. The electrical signal will change to different degrees due to the "impedance" value of each part of the human body, so as to detect the total water, protein, inorganic salts, body fat, muscle mass, fat-free weight, body weight, skeletal muscle content, body fat percentage, BMI, segmental muscle development, body circumference (chest circumference, waist circumference, right upper arm, left upper arm, right thigh, left thigh, neck circumference, hip circumference), muscle balance (upper limb, lower limb, upper and lower limb), body shape examination, segmental fat analysis, internal organs fat (grade), waist-to-hip ratio (WHR), health assessment, basal metabolic rate, nutritional assessment (edema, BMI, body fat percentage), weight control, fat control, muscle control, impedance value of each segment and frequency, various data indicators. 2. Experience innovation: The measured weight data is real-time. Various data of the body are measured within 26 seconds through various micro-current pulse modes, and the test is not carried out while operating the mobile phone. After adding the corresponding numerical information for the first time, the test can be carried out at any time. After opening the app, the updated test data can be watched. 3. Design Innovation: As a scale, the upper right corner of the display screen is very friendly for pregnant mothers and "big belly" people to measure their weight. 4. The trapezoidal-shaped body and the wrapped edge will not be overturned due to gravity imbalance during weighing, and it can also prevent the user's feet from colliding with the glass edge and contact causing pain and discomfort. 5. Material process innovation: ITO conductive film is used to replace the traditional metal electrode sheet, and the new processing process of frosted glass is more skin-friendly 6. Technical algorithm innovation: The measurement algorithm of the product belongs to the medical grade, which can be compared with the professional medical body composition analyzer. The accuracy is comparable to black technology.
