Frequency-domain reconstruction of signals in electrical bioimpedance spectroscopy

Abstract: The use of an amplitude/phase retrieval algorithm in electrical bioimpedance spectroscopy (EIS) that allows a new technique to reconstruct the impedance spectrum in the frequency-domain is reported. To the authors' knowledge this is the first time the proposed algorithm has been used to calculate the modulus or phase of a bioimpedance in EIS from one of these two experimentally obtained parameters. The algorithmic technique is demonstrated in EIS, when wide-bandwidth amplifiers,phase-detectors, and high speed … Show more

“…For the use of the phase/modulus retrieval algorithm in Z Cole (s) the independent term corresponding to the resistance, R ∞ , causes the frequency dependent function to satisfy neither the phase-nor the modulus-retrieval algorithm conditions (Hayes et al, 1980;Paterno et al, 2009). In other words, the experimental points to be used with the phase/modulus retrieval algorithm must be previously tested with known bioimpedance spectrum data to verify if the process is applicable.…”
