Compensation of impedance meters when using an external front-end amplifier
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002-04-30)
Article.
Accés obert
Article.
Accés obert
Four-terminal impedance meters based on
pseudo-bridges yield unexpected uncertainties when using high-contact-impedance electrodes. Adding a front-end amplifier to the impedance meter and rearranging the connection of the ...

Accés restringit per política de l'editorial
In this paper, we present a framework to analyze the propagation of measurement errors through the body composition equations. This is done through the equations for body composition assessment (BCA), for single/multifrequency ...
Usefulness of bioelectrical impedance analysis for monitoring patients with refractory ascites
(2019-01-01)
Article.
Accés obert
Article.
Accés obert
Background: bioelectrical impedance analysis is a technique
for the determination of the hydropic component. The
hydropic component, determined by blood volume, could
be a reflection of the hemodynamic situation. This ...
Different displacement of bioimpedance vector due to Ag/AgCl electrode effect
(2016-07-06)
Article.
Accés obert
Article.
Accés obert
BACKGROUND/OBJECTIVES: Bioelectrical impedance vector analysis (BIVA) is increasingly used in clinical research to assess soft
Q2 tissue hydration. It is known that physical characteristics of electrodes, such as low ...
Using temporal electrical impedance spectroscopy measures to differentiate lung pathologies with the 3-electrode method
(2022)

Comunicació de congrés.
Accés obert
Minimally invasive lung bioimpedance measurements could serve in the future diagnosis of lung pathologies complementing biopsies and imaging techniques. Through the electrical impedance spectroscopy (EIS) technique using ...
Alternative conducted emission measurements on mains without LISNs
(2015-12-01)
Article.
Accés obert
Article.
Accés obert
Conducted emission tests are always performed by the use of LISNs in laboratories in accordance with CISPR22, CISPR11 and other similar standards. However, it is not always possible to use LISNs because of some limitations. ...
Early detection of acute transmural myocardial ischemia by the phasic systolic-diastolic changes of local tissue electrical impedance
(2016-02-01)
Article.
Accés obert
Article.
Accés obert
Myocardial electrical impedance is influenced by the mechanical activity of the heart. Therefore, the ischemia-induced mechanical dysfunction may cause specific changes in the systolic-diastolic pattern of myocardial ...

Article.
Accés restringit per política de l'editorial
Measuring the impedance frequency response of systems by means of frequency sweep electrical impedance spectroscopy (EIS) takes time. An alternative based on broadband signals enables the user to acquire simultaneous ...
Longitudinal and transversal bioimpedance measurements in addition to diagnosis of heart failure
(2010)
Text en actes de congrés.
Accés obert
Text en actes de congrés.
Accés obert
Heart Failure (HF) is a clinical syndrome characterised by signs of systemic and
pulmonary fluid retention, shortness of breath and/or fatigue. There is a lack of reliable indicators of disease state. Benefits and ...
