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. 000160869 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T60-23R$$9info:eu-repo/grantAgreement/EUR/MINECO/TED2021-130374B-C22 000160869 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000160869 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000160869 700__ $$0(orcid)0000-0003-0832-6112$$aPonce de León Vázquez, Jesús 000160869 700__ $$0(orcid)0000-0002-7500-4650$$aBeltrán Blázquez, José Ramón$$uUniversidad de Zaragoza 000160869 7102_ $$15008$$2785$$aUniversidad de Zaragoza$$bDpto.
