This paper reports the validation of James One\u2019s EDA sensor by comparing its signal against a research grade polygraph. Twenty participants were instructed to perform breathing exercises to elicit the modulation of EDA and heart rate, while the physiological signal was captured simultaneously on James One and a Biopac MP36. The resulting EDA and PPG records collected from both systems were comprehensively compared. Results suggest that James One captures EDA signal with a quality comparable to a research grade equipment, this constituting a reliable means of capturing data while minimizing setup time and intrusiveness.<\/jats:p>","DOI":"10.3390\/s19224824","type":"journal-article","created":{"date-parts":[[2019,11,7]],"date-time":"2019-11-07T02:48:31Z","timestamp":1573094911000},"page":"4824","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Validation of Wireless Sensors for Psychophysiological Studies"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2800-3903","authenticated-orcid":false,"given":"Pedro","family":"Silva Moreira","sequence":"first","affiliation":[{"name":"Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, 4710-057 Braga, Portugal"},{"name":"ICVS\/3B\u2019s, PT Government Associate Laboratory, 4710-057 Braga\/Guimar\u00e3es, Portugal"},{"name":"MindProber Labs, 4450-102 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4201-5641","authenticated-orcid":false,"given":"Pedro","family":"Chaves","sequence":"additional","affiliation":[{"name":"MindProber Labs, 4450-102 Porto, Portugal"},{"name":"Department of Experimental Biology, Faculty of Medicine, University of Porto, 4200-319 Porto, Portugal"}]},{"given":"Ruben","family":"Dias","sequence":"additional","affiliation":[{"name":"MindProber Labs, 4450-102 Porto, Portugal"}]},{"given":"Nuno","family":"Dias","sequence":"additional","affiliation":[{"name":"MindProber Labs, 4450-102 Porto, Portugal"},{"name":"2Ai-Polytechnic Institute of C\u00e1vado and Ave, Campus do IPCA, 4750-810 Barcelos, Portugal"}]},{"given":"Pedro R","family":"Almeida","sequence":"additional","affiliation":[{"name":"MindProber Labs, 4450-102 Porto, Portugal"},{"name":"School of Criminology, Faculty of Law, University of Porto, 4050-123 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,6]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Psychophysiological science: Interdisciplinary approaches to classic questions about the mind","volume":"3","author":"Cacioppo","year":"2007","journal-title":"Handb.
