Development and Evaluation of the Innovative Smartphone Interface Bioelectrical Impedance Analyzer

Measuring body fat using BIA (Bioelectrical Impedance Analyzer) is becoming a popular method to check the body's composition and monitor a healthy diet [1]. There are a number of commercially available BIA products which can measure BFP (Body Fat Percentage) but the users often lose their interests due to carrying an additional device and lack of interaction with the device.
