Localized hamstring bioimpedance in marathon runners is related to muscle high-energy enzyme serum levels and predicts race time
(Frontiers Media SA, 2024-03-05)
Article
Open AccessIntroduction: The aim was to analyze the response of serum levels of inflammatory, high-energy muscle biomarkers and hamstring localized bioimpedance (L-BIA) measurements to marathon running and to ascertain whether they ... -
Real-time characterization of radiofrequency lesions by local multifrequency impedance with thermal correction
(Oxford University Press, 2024-05-24)
Article
Open AccessBackground/Introduction: Recent studies have shown that measuring local impedance (LI) at a single frequency can be useful for real-time characterization of radiofrequency (RF) lesion size during arrhythmia ablation ... -
Resilience of QPSK radio links under narrowband and broadband electromagnetic interferences
(Institute of Electrical and Electronics Engineers (IEEE), 2024)
Article
Open AccessElectromagnetic interference has the potential to affect the functionality and performance of radio communication links. This work investigates the impact electromagnetic disturbances have on such wireless links, taking ... -
A novel dual-parameter proximity and touch sensor using SiO2 nanoparticles and NaCl with commercial acrylic-based encapsulation
(Elsevier, 2024-06)
Article
Open AccessThis study shows the development and analysis of a novel capacity proximity sensor (CPS) based on a sensing layer made up of a mixture of silicon dioxide nanoparticles (SiO2) and sodium chloride (NaCl), and an encapsulation ... -
MEMS miniaturized low-noise magnetic field sensor for the observation of sub-millihertz magnetic fluctuations in space exploration
(Elsevier, 2024-05-15)
Article
Open AccessThe objective of this paper is to show that, using magnetic field modulation with a MEMS resonator, it is possible to reduce the noise floor of a commercial Tunneling Magnetic Resistance by one order of magnitude, in the ... -
Sensor noise in LISA Pathfinder: laser frequency noise and its coupling to the optical test mass readout
(American Physical Society, 2024-02-15)
Article
Open AccessThe LISA Pathfinder (LPF) mission successfully demonstrated the feasibility of the technology needed for the future space borne gravitational wave observatory LISA. A key subsystem under study was the laser interferometer, ... -
On the use of fractional calculus to improve the pulse arrival time (PAT) detection when using photoplethysmography (PPG) and electrocardiography (ECG) signals
(Public Library of Science (PLOS), 2024-02-16)
Article
Open AccessThe pulse arrival time (PAT) has been considered a surrogate measure for pulse wave velocity (PWV), although some studies have noted that this parameter is not accurate enough. Moreover, the inter-beat interval (IBI) time ... -
Electrical impedance tomography to measure spirometry parameters in chronic obstructive pulmonary disease patients
(Sociedad Mexicana de Ingeniería Biomedíca, 2022-12-01)
Article
Open AccessSpirometry is a test for the diagnosis of chronic obstructive pulmonary disease. It is a technique that can be intolerant due to the essential use of a mouthpiece and a clamp. This study proposes the use of electrical ... -

Tilt-to-length coupling in LISA Pathfinder: a data analysis
(American Physical Society, 2023-11-15)
Article
Open AccessWe present a study of the tilt-to-length coupling noise during the LISA Pathfinder mission and how it depended on the system’s alignment. Tilt-to-length coupling noise is the unwanted coupling of angular and lateral ... -
