摘要

To provide an electronic system and method for bioimpedance signal acquisition.SOLUTION: A current signal injection module 10 generates a current signal S1 to be applied to a subject. A bioimpedance signal measurement module 20 measures a bioimpedance signal S2 based on a voltage generated by the current signal S1. A data quality detection module 30 is configured for detecting an AC and/or DC level of the measured bioimpedance signal S2 and detects whether the AC and/or DC level is within or without an AC reference value range and/or a DC reference value range, respectively. A signal adaptation module 40 modifies at least one parameter of the current signal injection module 10 and/or the bioimpedance signal measurement module 20 based on the detection of whether the AC and/or DC level is within or without an AC reference value range and/or a DC reference value range, respectively.SELECTED DRAWING: Figure 1
