Its applications include perception, learning, memory, language, decision making and neural network mapping. Recently, interest has surged in extending EEG measurements to domestic environments. However, the high costs associated with traditional laboratory EEG systems have hindered accessibility for many individuals and researchers in education, research, and medicine. To tackle this, a mobile-EEG device named \u201cDreamMachine\u201d was developed. A more affordable alternative to both lab-based EEG systems and existing mobile-EEG devices. This system boasts 24 channels, 24-bit resolution, up to 6 h of battery life, portability, and a low price. Our open-source and open-hardware approach empowers cognitive neuroscience, especially in education, learning, and research, opening doors to more accessibility. This paper introduces the DreamMachine\u2019s design and compares it with the lab-based EEG system \u201casalabTM\u201d in an eyes-open and eyes-closed experiment. The Alpha band exhibited higher power in the power spectrum during eyes-closed conditions, whereas the eyes-open condition showed increased power specifically within the Delta frequency range. Our analysis confirms that the DreamMachine accurately records brain activity, meeting the necessary standards when compared to the asalabTM system.<\/jats:p>","DOI":"10.3390\/s23177440","type":"journal-article","created":{"date-parts":[[2023,8,28]],"date-time":"2023-08-28T06:10:22Z","timestamp":1693203022000},"page":"7440","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Introducing a New Mobile Electroencephalography System and Evaluating Its Quality in Comparison to Clinical Electroencephalography"],"prefix":"10.3390","volume":"23","author":[{"given":"Paria","family":"Samimisabet","sequence":"first","affiliation":[{"name":"Institute of Cognitive Science, Osnabrueck University, 49074 Osnabr\u00fcck, Germany"}]},{"given":"Laura","family":"Krieger","sequence":"additional","affiliation":[{"name":"Institute of Cognitive Science, Osnabrueck University, 49074 Osnabr\u00fcck, Germany"}]},{"given":"Themis","family":"Nethar","sequence":"additional","affiliation":[{"name":"Institute of Cognitive Science, Osnabrueck University, 49074 Osnabr\u00fcck, Germany"}]},{"given":"Gordon","family":"Pipa","sequence":"additional","affiliation":[{"name":"Institute of Cognitive Science, Osnabrueck University, 49074 Osnabr\u00fcck, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"78060","DOI":"10.1109\/ACCESS.2021.3083519","article-title":"Impact of eeg parameters detecting dementia diseases: A systematic review","volume":"9","year":"2021","journal-title":"IEEE Access"},{"key":"ref_2","unstructured":"Chernecky, C.C., and Berger, B.J.
