Therefore, extensive research on the genesis of motion artifacts in EEG recordings is still needed to optimize existing technologies, shedding light on possible solutions to overcome the current limitations. We identified three potential sources of motion artifacts occurring at three different levels of a traditional biopotential acquisition chain: the skin-electrode interface, the connecting cables between the detection and the acquisition systems, and the electrode-amplifier system. The identified sources of motion artifacts were modelled starting from experimental observations carried out on EEG signals. Consequently, we designed customized EEG electrode systems aiming at experimentally disentangling the possible causes of motion artifacts. Both analytical and experimental observations indicated two main residual sites responsible for motion artifacts: the connecting cables between the electrodes and the amplifier and the sudden changes in electrode-skin impedance due to electrode movements. We concluded that further advancements in EEG technology should focus on the transduction stage of the biopotentials amplification chain, such as the electrode technology and its interfacing with the acquisition system.<\/jats:p>","DOI":"10.3390\/s24196363","type":"journal-article","created":{"date-parts":[[2024,9,30]],"date-time":"2024-09-30T12:06:32Z","timestamp":1727697992000},"page":"6363","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Motion Artifacts in Dynamic EEG Recordings: Experimental Observations, Electrical Modelling, and Design Considerations"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1311-1389","authenticated-orcid":false,"given":"Alessandra","family":"Giangrande","sequence":"first","affiliation":[{"name":"Laboratory of Neuromuscular System and Rehabilitation Engineering, Department of Electronics and Telecommunications, Politecnico di Torino, 10129 Turin, Italy"},{"name":"Faculty of Sport and Health Sciences, University of Jyv\u00e4skyl\u00e4, 40014 Jyv\u00e4skyl\u00e4, Finland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4797-0667","authenticated-orcid":false,"given":"Alberto","family":"Botter","sequence":"additional","affiliation":[{"name":"Laboratory of Neuromuscular System and Rehabilitation Engineering, Department of Electronics and Telecommunications, Politecnico di Torino, 10129 Turin, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6866-6587","authenticated-orcid":false,"given":"Harri","family":"Piitulainen","sequence":"additional","affiliation":[{"name":"Faculty of Sport and Health Sciences, University of Jyv\u00e4skyl\u00e4, 40014 Jyv\u00e4skyl\u00e4, Finland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5295-5314","authenticated-orcid":false,"given":"Giacinto Luigi","family":"Cerone","sequence":"additional","affiliation":[{"name":"Laboratory of Neuromuscular System and Rehabilitation Engineering, Department of Electronics and Telecommunications, Politecnico di Torino, 10129 Turin, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3526","DOI":"10.1152\/jn.00105.2010","article-title":"Removal of movement artifact from high-density EEG recorded during walking and running","volume":"103","author":"Gwin","year":"2010","journal-title":"J.
