Active flexible concentric ring electrode for non-invasive surface bioelectrical recordings

Prats Boluda, Gema; Ye Lin, Yiyao; García Breijo, Eduardo; Ibáñez Civera, Francisco Javier; Garcia Casado, Francisco Javier (IOP Publishing Ltd, 2012-11-15)

Bioelectrical surface recordings are usually performed by unipolar or bipolar disc electrodes even though they entail the serious disadvantage of having poor spatial resolution. Concentric ring electrodes give improved ...
Comprehensive Optimization of the Tripolar Concentric Ring Electrode Based on Its Finite Dimensions Model and Confirmed by Finite Element Method Modeling

Makeyev, Oleksandr; Ye Lin, Yiyao; Prats-Boluda, Gema; Garcia-Casado, Javier (MDPI AG, 2021-08-31)

[EN] The optimization performed in this study is based on the finite dimensions model of the concentric ring electrode as opposed to the negligible dimensions model used in the past. This makes the optimization problem ...
Estudio de la actividad onda lenta gástrica no-invasiva mediante electrodos concéntricos anulares

Jareño Silvestre, Alejandro (Universitat Politècnica de València, 2019-10-07)

[ES] El electrogastrograma (EGG) es el registro no-invasivo de la actividad mioeléctrica gástrica mediante electrodos de contacto en la superficie abdominal en el estómago. La simplicidad y seguridad de EGG lo hacen atractivo ...
Evaluation of Bipolar, Tripolar, and Quadripolar Laplacian Estimates of Electrocardiogram via Concentric Ring Electrodes

Garcia-Casado, Javier; Ye Lin, Yiyao; Prats-Boluda, Gema; Makeyev, Oleksandr (MDPI AG, 2019-09-01)

[EN] Surface Laplacian estimates via concentric ring electrodes (CREs) have proven to enhance spatial resolution compared to conventional disc electrodes, which is of great importance for P-wave analysis. In this study, ...
Evaluation of Respiratory Muscle Activity by Means of Concentric Ring Electrodes

Estrada-Petrocelli, Luis; Torres, Abel; Sarlabous, Leonardo; Ràfols-de-Urquía, Magda; Ye Lin, Yiyao; Prats-Boluda, Gema; Jané, Raimon; Garcia-Casado, Javier (Institute of Electrical and Electronics Engineers, 2021-03)

[EN] Surface electromyography (sEMG) can be used for the evaluation of respiratory muscle activity. Recording sEMG involves the use of surface electrodes in a bipolar configuration. However, electrocardiographic (ECG) ...
Evaluation of Swallowing Related Muscle Activity by Means of Concentric Ring Electrodes

Garcia-Casado, Javier; Prats-Boluda, Gema; Ye Lin, Yiyao; Restrepo-Agudelo, Sebastián; Perez-Giraldo, Estefanía; Orozco-Duque, Andrés (MDPI AG, 2020-09)

[EN] Surface electromyography (sEMG) can be helpful for evaluating swallowing related muscle activity. Conventional recordings with disc electrodes suffer from significant crosstalk from adjacent muscles and electrode-to-muscle ...
Identification of atrial fibrillation drivers by means of concentric ring electrodes

Prats-Boluda, Gema; Guillem Sánchez, María Salud; Rodrigo, Miguel; Ye-Lin, Yiyao; Garcia-Casado, Javier (Elsevier, 2022-09)

[EN] Background and objective: The prevalence of atrial fibrillation (AF) has tripled in the last 50 years due to population aging. High-frequency (DFdriver) activated atrial regions lead the activation of the rest of the ...
Validating the Comparison Framework for the Finite Dimensions Model of Concentric Ring Electrodes Using Human Electrocardiogram Data

Makeyev, Oleksandr; Musngi, Mark; Moore, Larry; Ye Lin, Yiyao; Prats-Boluda, Gema; Garcia-Casado, Javier (MDPI AG, 2019-10-12)

[EN] While progress has been made in design optimization of concentric ring electrodes maximizing the accuracy of the surface Laplacian estimation, it was based exclusively on the negligible dimensions model of the electrode. ...
