Abstract
A technique for determining skin sodium content using bioimpedance spectroscopy includes applying a current at a predetermined frequency to skin of a subject, measuring a voltage across the skin of the subject produced by the current, determining a resistance across the skin of the subject at the predetermined frequency using the measured voltage, and determining skin sodium content using the measured voltage.
