A comparison of heartbeat detectors for the seismocardiogram
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Comunicació de congrés
Accés obertThe study aimed to study the accuracy in RR time series derived from the seismocardiogram when employing different heartbeat detectors in subjects measured in a quiet environment. The ECG and seismocardiogram of 17 healthy ... -
Biological tissue characterization by magnetic induction spectroscopy (MIS): requirements and limitations
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2003-07-31)
Article
Accés obertMagnetic induction spectroscopy (MIS) aims at the contactless measurement of the passive electrical properties (PEP) σ, ε, and μ of biological tissues via magnetic fields at multiple frequencies. Whereas previous publications ... -
On the feasibility of noncontact ECG measurements
(2016-03-01)
Article
Accés obertThe article by Kranjec et al. [1], “Novel methods of noncontact heart rate measurement: A feasibility study” is interesting and informative as it compares different contactless methods for heart rate detection. Nevertheless, ... -
Reduction of motion artifacts using a two-frequency impedance plethysmograph and adaptative filtering
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1995-10-01)
Article
Accés obertWe measured transthoracic impedance in nine presumed healthy adult subjects with a two-frequency plethysmograph at 57 kHz and 185 kHz. The measurement protocol included periods of normal breathing without motion and periods ... -
Respiratory rate detection by empirical mode decomposition method applied to diaphragm mechanomyographic signals
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialNon-invasive evaluation of respiratory activity is an area of increasing research interest, resulting in the appearance of new monitoring techniques, ones of these being based on the analysis of the diaphragm mechanomyographic ... -
Signal-to-motion artifact ratio versus frequency for impedance pneumography
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1995-03-01)
Article
Accés obertWe measured transthoracic impedance between 12.5 and 185 kHz in nine adults. We used a system with two impedance channels, both simultaneously detecting the real part of impedance at two different frequencies. We used only ...
