In this work, EMIS measurements of pristine and damaged adhesive joints were performed, and \nfeatures were extracted from the experimental measurements. These features were inputted to a k-Nearest Neighbors (kNN) model for damage\n detection. Results show that only one type of features is enough for damage detection. Furthermore, the use of the Manhattan Distance in the kNN enables a better classification.<\/jats:p>","DOI":"10.24840\/2183-6493_002-001_2758","type":"journal-article","created":{"date-parts":[[2024,10,11]],"date-time":"2024-10-11T09:41:47Z","timestamp":1728639707000},"page":"2-13","source":"Crossref","is-referenced-by-count":0,"title":["Void detection in structural adhesive joints using a k-Nearest Neighbors model with features from Electromechanical Impedance Spectroscopy"],"prefix":"10.24840","volume":"2","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-2082-1972","authenticated-orcid":false,"given":"Pedro A.
