The sensing system is integrated into a smart vest for an untethered, low-cost and comfortable breathing monitoring of Chronic Obstructive Pulmonary Disease (COPD) patients during the rest period between respiratory rehabilitation exercises at home. To provide an extensible solution to the remote monitoring using this sensor and other devices, the design and preliminary development of an e-Health platform based on the Internet of Medical Things (IoMT) paradigm is also presented. In order to validate the proposed solution, two quasi-experimental studies have been developed, comparing the estimations with respect to the golden standard. In a first study with healthy subjects, the mean value of the respiratory rate error, the standard deviation of the error and the correlation coefficient were 0.01 breaths per minute (bpm), 0.97 bpm and 0.995 (p &lt; 0.00001), respectively. In a second study with COPD patients, the values were \u22120.14 bpm, 0.28 bpm and 0.9988 (p &lt; 0.0000001), respectively. The results for the rest period show the technical and functional feasibility of the prototype and serve as a preliminary validation of the device for respiratory rate monitoring of patients with COPD.<\/jats:p>","DOI":"10.3390\/s18072144","type":"journal-article","created":{"date-parts":[[2018,7,3]],"date-time":"2018-07-03T11:12:58Z","timestamp":1530616378000},"page":"2144","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":77,"title":["Smart Vest for Respiratory Rate Monitoring of COPD Patients Based on Non-Contact Capacitive Sensing"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7636-2855","authenticated-orcid":false,"given":"David","family":"Naranjo-Hern\u00e1ndez","sequence":"first","affiliation":[{"name":"Biomedical Engineering Group, University of Seville, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5047-5296","authenticated-orcid":false,"given":"Alejandro","family":"Talaminos-Barroso","sequence":"additional","affiliation":[{"name":"Biomedical Engineering Group, University of Seville, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6853-4899","authenticated-orcid":false,"given":"Javier","family":"Reina-Tosina","sequence":"additional","affiliation":[{"name":"Biomedical Engineering Group, University of Seville, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9221-0299","authenticated-orcid":false,"given":"Laura M.","family":"Roa","sequence":"additional","affiliation":[{"name":"Biomedical Engineering Group, University of Seville, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4383-9394","authenticated-orcid":false,"given":"Gerardo","family":"Barbarov-Rostan","sequence":"additional","affiliation":[{"name":"Biomedical Engineering Group, University of Seville, 41092 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0939-5427","authenticated-orcid":false,"given":"Pilar","family":"Cejudo-Ramos","sequence":"additional","affiliation":[{"name":"Medical-Surgical Unit of Respiratory Diseases, University Hospital Virgen del Roc\u00edo, 41013 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo","family":"M\u00e1rquez-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Medical-Surgical Unit of Respiratory Diseases, University Hospital Virgen del Roc\u00edo, 41013 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1902-0522","authenticated-orcid":false,"given":"Francisco","family":"Ortega-Ruiz","sequence":"additional","affiliation":[{"name":"Medical-Surgical Unit of Respiratory Diseases, University Hospital Virgen del Roc\u00edo, 41013 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2011","DOI":"10.1371\/journal.pmed.0030442","article-title":"Projections of global mortality and burden of disease from 2002 to 2030","volume":"3","author":"Mathers","year":"2006","journal-title":"PLoS Med."},{"key":"ref_2","unstructured":"Global Initiative for Chronic Obstructive Lung Disease (GOLD) (2018, July 02).
