Abstract
A system may comprise: an excitation current source; a first electrode coupled to the excitation current source; and a second electrode coupled to the excitation current source. The first and second electrodes may be configured to pass an excitation current from the excitation current source through a human body. First and second calibration resistors may be coupled to and positioned between the excitation current source and the first electrode. Third and fourth calibration resistors may be coupled to and positioned between the excitation current source and the second electrode. The system may also comprise a sensor configured to measure voltages across each of the first, second, third, and fourth calibration resistors.
