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.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/ECGoxygen saturationreconfigurable instrumentationwearable instrumentsElectrocardiographyElectrocardiography, AmbulatoryHumansMonitoring, PhysiologicOximetrySignal Processing, Computer-AssistedWearable Electronic Devicesresearch article30986953open access10.3390/s190715901424-8220PMC6479924https://www.mdpi.com/1424-8220/19/7/1590/pdf?version=1554195588https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6479924/pdf
