Wrist-wearable bioelectrical impedance analyzer with miniature electrodes for daily obesity management

Abstract Bioelectrical impedance analysis (BIA) is used to analyze human body composition by applying a small alternating current through the body and measuring the impedance. The smaller the electrode of a BIA device, the larger the impedance measurement error due to the contact resistance between...
