Here, Ag\/AgCl electrodes with conductive gels are usually used in a 12-lead ECG system to access biopotentials. However, using Ag\/AgCl electrodes with conductive gels might be inconvenient in a prehospital setting. In previous studies, several dry electrodes have been developed to improve this issue. However, these dry electrodes have contact with the skin directly, and they might be still unsuitable for patients with wounds. In this study, a wearable 12-lead electrocardiogram monitoring system was proposed to improve the above issue. Here, novel noncontact electrodes were also designed to access biopotentials without contact with the skin directly. Moreover, by using the mechanical design, this system allows the user to easily wear and take off the device and to adjust the locations of the noncontact electrodes. The experimental results showed that the proposed system could exactly provide a good ECG signal quality even while walking and could detect the ECG features of the patients with myocardial ischemia, installation pacemaker, and ventricular premature contraction.<\/jats:p>","DOI":"10.3390\/s19071509","type":"journal-article","created":{"date-parts":[[2019,3,29]],"date-time":"2019-03-29T03:38:52Z","timestamp":1553830732000},"page":"1509","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Design of a Wearable 12-Lead Noncontact Electrocardiogram Monitoring System"],"prefix":"10.3390","volume":"19","author":[{"given":"Chien-Chin","family":"Hsu","sequence":"first","affiliation":[{"name":"Department of Emergency Medicine, Chi Mei Medical Center, Tainan 710, Taiwan"},{"name":"Department of Biotechnology, Southern Taiwan University of Science and Technology, Tainan 71005, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0498-3190","authenticated-orcid":false,"given":"Bor-Shing","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, National Taipei University, New Taipei 23741, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke-Yi","family":"He","sequence":"additional","affiliation":[{"name":"Institute of Imaging and Biomedical Photonics, National Chiao Tung University, Tainan 711, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8653-2571","authenticated-orcid":false,"given":"Bor-Shyh","family":"Lin","sequence":"additional","affiliation":[{"name":"Institute of Imaging and Biomedical Photonics, National Chiao Tung University, Tainan 711, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"271","DOI":"10.1088\/0967-3334\/21\/2\/307","article-title":"A direct comparison of wet, dry and insulating bioelectric recording electrodes","volume":"21","author":"Searle","year":"2000","journal-title":"Physiol.
