Adapted from a previous headband model, MsW2 has been optimized for wrist-based applications. Its efficacy was validated through experiments with 25 participants, comparing its EDA measurements with the Empatica E4 device. The results demonstrated high coherence between the two systems. Additionally, a simplified skin impedance model was proposed and validated, providing a reliable means of analyzing EDA data. The wearable demonstrates significant potential for applications in emotion detection, health monitoring, and more. info:eu-repo/grantAgreement/ES/DGA/T60-23R info:eu-repo/grantAgreement/EUR/MINECO/TED2021-130374B-C22 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ponce de León Vázquez, Jesús (orcid)0000-0003-0832-6112 Beltrán Blázquez, José Ramón Universidad de Zaragoza (orcid)0000-0002-7500-4650 5008 785 Universidad de Zaragoza Dpto.
