Title:
SYSTEM FOR MEASURING BIOIMPEDANCE, BIOIMPEDANCE MEASUREMENT METHOD, AND COMPUTER-READABLE RECORDING MEDIUM FOR EXECUTING SAME
Document Type and Number:
WIPO Patent Application WO/2021/215609
Kind Code:
A1
Abstract:
A system for measuring bioimpedance, a bioimpedance measurement method, and a computer-readable recording medium for executing same in embodiments may comprise an electric current supply device for supplying an electric current to a human body, and a readout IC (ROIC) which in response to the supply of electric current, extracts an AC signal by attenuating a DC signal in a voltage generated from the human body, and amplifies and outputs the AC signal. The embodiments may implement an efficient system capable of improving energy efficiency while being able to simultaneously use two types of signals, AC impedance and DC impedance signals.
