These devices can accurately detect and identify different substances and gases based on their chemical composition. This can be incredibly useful in fields such as environmental monitoring and industrial food applications, where the quality and safety of products or ecosystems should be ensured through a precise analysis. Traditionally, this task is performed by an expert panel or by using laboratory tests but sometimes becomes a bottleneck because of time and other human factors that can be solved with technologies such as the provided by electronic tongue and nose devices. Additionally, these devices can be used in medical diagnosis, quality monitoring, and even in the automotive industry to detect gas leaks. The possibilities are endless, and as these technologies continue to improve, they will undoubtedly play an increasingly important role in improving our lives and ensuring our safety. Because of the multiple applications and developments in this field in the last years, this work will present an overview of the electronic tongues and noses from the point of view of the approaches developed and the methodologies used in the data analysis and steps to this aim. In the same manner, this work shows some of the applications that can be found in the use of these devices and ends with some conclusions about the current state of these technologies.<\/jats:p>","DOI":"10.3390\/bios14040190","type":"journal-article","created":{"date-parts":[[2024,4,15]],"date-time":"2024-04-15T03:56:13Z","timestamp":1713153373000},"page":"190","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":66,"title":["Electronic Tongues and Noses: A General Overview"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4498-596X","authenticated-orcid":false,"given":"Diego","family":"Tibaduiza","sequence":"first","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maribel","family":"Anaya","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-8657-2561","authenticated-orcid":false,"given":"Johan","family":"G\u00f3mez","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-6204-3123","authenticated-orcid":false,"given":"Juan","family":"Sarmiento","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-7225-025X","authenticated-orcid":false,"given":"Maria","family":"Perez","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristhian","family":"Lara","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johan","family":"Ruiz","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolas","family":"Osorio","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katerin","family":"Rodriguez","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Qu\u00edmica y Ambiental, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isaac","family":"Hernandez","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos","family":"Sanchez","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda El\u00e9ctrica y Electr\u00f3nica, Universidad Nacional de Colombia, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"149926","DOI":"10.1016\/j.cej.2024.149926","article-title":"Progress and challenges in flexible capacitive pressure sensors: Microstructure designs and applications","volume":"485","author":"Yuan","year":"2024","journal-title":"Chem.
