With the intent of providing a novel approach to the field, in this paper we discuss the development of a wearable system for the acquisition of EEG signals based on a portable, low-power custom PCB specifically designed to be used in combination with non-conventional ultra-conformable and imperceptible Parylene-C tattoo electrodes. The proposed system has been tested in a standard rest-state experiment, and its performance in terms of discrimination of two different states has been compared to that of a commercial wearable device for EEG signal acquisition (i.e., the Muse headset), showing comparable results. This first preliminary validation demonstrates the possibility of conveniently employing ultra-conformable tattoo-electrodes integrated portable systems for the unobtrusive acquisition of brain activity.<\/jats:p>","DOI":"10.3390\/s23020766","type":"journal-article","created":{"date-parts":[[2023,1,10]],"date-time":"2023-01-10T01:57:48Z","timestamp":1673315868000},"page":"766","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Wearable System Based on Ultra-Thin Parylene C Tattoo Electrodes for EEG Recording"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4185-7225","authenticated-orcid":false,"given":"Antonello","family":"Mascia","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronics Engineering, University of Cagliari, Piazza D\u2019Armi, 09123 Cagliari, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7895-5956","authenticated-orcid":false,"given":"Riccardo","family":"Collu","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, University of Cagliari, Piazza D\u2019Armi, 09123 Cagliari, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0331-7516","authenticated-orcid":false,"given":"Andrea","family":"Spanu","sequence":"additional","affiliation":[{"name":"Department of Science, Technology and Society, Scuola Universitaria Superiore IUSS, Palazzo del Broletto, Piazza della Vittoria 15, 27100 Pavia, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2784-6527","authenticated-orcid":false,"given":"Matteo","family":"Fraschini","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, University of Cagliari, Piazza D\u2019Armi, 09123 Cagliari, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6136-7664","authenticated-orcid":false,"given":"Massimo","family":"Barbaro","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, University of Cagliari, Piazza D\u2019Armi, 09123 Cagliari, Italy"}]},{"given":"Piero","family":"Cosseddu","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, University of Cagliari, Piazza D\u2019Armi, 09123 Cagliari, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Aroganam, G., Manivannan, N., and Harrison, D.
