SYSTEM AND METHOD FOR MEASURING BIO-IMPEDANCE

WIPO Patent Application WO/2022/098219

A1

A system for measuring bio-impedance according to an embodiment may comprise: a current supply unit that supplies current to a human body; and an ROIC that extracts an AC signal by removing a DC signal from among the DC signal and the AC signal output from the human body. The embodiment has an effect of amplifying only the AC signal with a large gain by effectively removing the DC signal.
