The System of Portable Fat Detector With Dual-wavelength Near-infrared Light

In recent years, the incidence of obesity is increasing year by year, and the trend accelerates quickly. Obesity is frequently concomitance with diabetes, fatty liver, blood lipid disorders, hypertension, coronary heart disease and other chronic diseases. So a self-serviced, portable and simple body composition testing apparatus is highly valued. The existing methods have some disadvantages, such as expensive, time-consuming, test condition rigor, suffer some pain or schlep uncomfortable. This paper describes the use of near-infrared technology develop portable fat thickness measurement instrument, to achieve body subcutaneous fat thickness which is a key parameter of body fat content. The method has the advantages such as simple, fast and visual.
