About<\/h2>\n
\n\n\n\n\n

The group\u2019s research addresses the design and development of advanced signal processing techniques and the interpretation of biomedical signals to improve non-invasive monitoring, diagnosis, disease prevention and pathology treatment.<\/strong><\/h4>\n\n\n\n
\n

The group focuses its research in a translational way to promote the transfer of our scientific and technological contributions. <\/span><\/p>\n<\/blockquote>\n\n\n\n

Currently, our prototypes are used in hospitals for research purposes and for future industrial developments. <\/span><\/p>\n\n\n\n

Our main objective is to improve diagnosis capability through the characterization of physiological phenomena and to enhance early detection of major cardiac and respiratory diseases and sleep disorders. We propose and design new signal processing algorithms and develop new biosignal databases, with the collaboration of our hospital partners. <\/span><\/p>\n\n\n\n

To validate the clinical information of new surface signals, we have developed specific invasive\/non-invasive protocols and animal models. <\/span><\/p>\n\n\n\n

        Novel method for differentiating normal from adventitious respiratory sounds (RS) to improve the diagnosis of pulmonary diseases. Particularly, continuous adventitious sounds (CAS) are of clinical interest because they reflect the severity of certain diseases. The new method is based on the multi-scale analysis of instantaneous frequency (IF) and envelope (IE) calculated after ensemble empirical mode decomposition (EEMD) of respiratory sounds.
