In this paper, the realization of the core of this system, i.e., the Cardiac Health Assessment and Monitoring Platform (CHAMP), with respect to its hardware, firmware, and wireless design features, is presented. The feature values from the CHAMP system have been correlated with myo-cardiac functions obtained from actual heart failure (HF) patients. The usability of this MCG-based cardiac health monitoring smart clothing system has also been evaluated with technology acceptance model (TAM) analysis and the results indicate that the subject shows a positive attitude toward using this wearable MCG-based cardiac health monitoring and early warning system.<\/jats:p>","DOI":"10.3390\/s18103538","type":"journal-article","created":{"date-parts":[[2018,10,19]],"date-time":"2018-10-19T10:08:02Z","timestamp":1539943682000},"page":"3538","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Realization and Technology Acceptance Test of a Wearable Cardiac Health Monitoring and Early Warning System with Multi-Channel MCGs and ECG"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5748-0151","authenticated-orcid":false,"given":"Wen-Yen","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Center for Biomedical Engineering, Chang Gung University, Tao-Yuan 33302, Taiwan"},{"name":"Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, Linkou, Tao-Yuan 33305, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong-Lin","family":"Ke","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Center for Biomedical Engineering, Chang Gung University, Tao-Yuan 33302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Cheng","family":"Chou","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Center for Biomedical Engineering, Chang Gung University, Tao-Yuan 33302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Po-Cheng","family":"Chang","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, Linkou, Tao-Yuan 33305, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsai-Hsuan","family":"Tsai","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, Linkou, Tao-Yuan 33305, Taiwan"},{"name":"Department of Industrial Design, Chang Gung University, Tao-Yuan 33302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2031-0183","authenticated-orcid":false,"given":"Ming-Yih","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, Linkou, Tao-Yuan 33305, Taiwan"},{"name":"Graduate Institute of Medical Mechatronics, Center for Biomedical Engineering, Chang Gung University, Tao-Yuan 33302, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sarlabous, L., Torres, A., Fiz, J.A., and Jane, R.
