However, specialized wearable devices remain an open field for high-risk professionals, such as military personnel, fire and rescue, law enforcement, etc. In this work, a prototype wearable instrument, based on reconfigurable technologies and capable of monitoring electrocardiogram, oxygen saturation, and motion, is presented. This reconfigurable device allows a wide range of applications in conjunction with mobile devices. As a proof-of-concept, the reconfigurable instrument was been integrated into ad hoc glasses, in order to illustrate the non-invasive monitoring of the user. The performance of the presented prototype was validated against a commercial pulse oximeter, while several alternatives for QRS-complex detection were tested. For this type of scenario, clustering-based classification was found to be a very robust option.<\/jats:p>","DOI":"10.3390\/s19071590","type":"journal-article","created":{"date-parts":[[2019,4,3]],"date-time":"2019-04-03T03:39:28Z","timestamp":1554262768000},"page":"1590","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Wearable System for Biosignal Acquisition and Monitoring Based on Reconfigurable Technologies"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6720-3476","authenticated-orcid":false,"given":"V\u00edctor","family":"Toral","sequence":"first","affiliation":[{"name":"Department of Electronics and Computer Technology, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3533-4660","authenticated-orcid":false,"given":"Antonio","family":"Garc\u00eda","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Technology, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1582-9626","authenticated-orcid":false,"given":"Francisco J.","family":"Romero","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Technology, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3294-8934","authenticated-orcid":false,"given":"Diego P.","family":"Morales","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Technology, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6476-8105","authenticated-orcid":false,"given":"Encarnaci\u00f3n","family":"Castillo","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Technology, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8126-1146","authenticated-orcid":false,"given":"Luis","family":"Parrilla","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Technology, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9153-4929","authenticated-orcid":false,"given":"Francisco M.","family":"G\u00f3mez-Campos","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Technology, University of Granada, 18071 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Morillas","sequence":"additional","affiliation":[{"name":"Hospital de Alta Resoluci\u00f3n de Guadix, 18500 Guadix, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alejandro","family":"S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Mando de Adiestramiento y Doctrina, Ej\u00e9rcito de Tierra, 18010 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Fotiadis, D.I., Glaros, C., and Likas, A.
