Bioimpedance calibration method including current leakage

Abstract Bioimpedance (BioZ) sensing serve as the foundation for numerous healthcare applications, enabling characterization and monitoring across a variety of medical use cases and contexts. At high frequencies, measured BioZ data often contain experimental artifacts caused by current leakage from stray load losses, resulting in reduced accuracy and reliability of the measurements. Here, we present a generalized nonlinear modeling framework for calibrating BioZ including stray load disturbances.
