Estado del arte para la detección de olores mediante el sensor cyranose 320 en Ecuador

Abstract

Electronic noses (e-noses) promise to be a largescale screening method, offering advantages such as: i) low cost, ii) non-invasive, iii) real-time analysis, among others. Motivation for which a state of the art has been proposed in order to identify the types of sensors and e-noses that have been used in the analysis of Volatile Organic Compounds (VOCs) of cancer patients, applying two methodologies, systematic mapping (SM) to collect the scientific journals with more relevance from 2015 to 2023; and systematic literature review (SLR), in which by building a taxonomy was provided for this paper: (i) composites and concentrations (ii) data preprocessing methods, (iii) data compression methods, (iv) feature selection and extraction methods, (v) machine learning algorithms, (vi) cross-validation methods, and (vii) evaluation metrics. Obtaining results that boost this technology in clinical practice, de Leon-Mart´ınez de Leon-Mart´ınez said [1] the study with the best quantitative results, presenting sensitivity, specificity, precision and area under the curve (AUC) of 100%, 100%, 100% and 1, respectively. However, scientific articles are required to perform external validation in order to position this device as a reliable form of screening in the medical field.
