We report a fully-wearable medical garment for mobile monitoring of cardiac biopotentials from the wrists or the neck with minimum restriction to regular clothing habits. The wearable prototype is based on elastic bands with graphene functionalized, textile electrodes and battery-powered, low-cost electronics for signal acquisition and wireless transmission. Comparison of the electrocardiogram (ECG) recordings obtained from the wearable prototype against conventional wet electrodes indicate excellent conformity and spectral coherence among the two signals.<\/jats:p>","DOI":"10.3390\/s17040875","type":"journal-article","created":{"date-parts":[[2017,4,18]],"date-time":"2017-04-18T11:22:04Z","timestamp":1492514524000},"page":"875","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":149,"title":["Intelligent Medical Garments with Graphene-Functionalized Smart-Cloth ECG Sensors"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4328-5985","authenticated-orcid":false,"given":"Murat","family":"Yapici","sequence":"first","affiliation":[{"name":"Faculty of Engineering and Natural Sciences, Sabanc\u0131 University, Istanbul 34956, Turkey"},{"name":"Sabanc\u0131 University Nanotechnology Research and Application Center, Istanbul 34956, Turkey"},{"name":"Department of Electrical Engineering, University of Washington, Seattle, WA 98195, USA"}]},{"given":"Tamador","family":"Alkhidir","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Khalifa University, Abu Dhabi 127788, UAE"}]}],"member":"1968","published-online":{"date-parts":[[2017,4,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.compbiomed.2014.08.014","article-title":"Heart monitoring systems\u2014A review","volume":"54","author":"Jain","year":"2014","journal-title":"Comput.
