The sepiolite layer is composed of tubes that have a length of several microns, and the diameter of the single tube ranges from several to tens of nanometers. The sepiolite layer itself demonstrated no chemical activity in the presence of volatile organic compounds (VOC), and the passive filter made of this material did not modify the chemical composition of the gaseous atmosphere diffusing to the gas-sensitive layer. The test results revealed that the structural remodelling of the sepiolite that occurs under the influence of temperature, as well as the effect of the filter (a compound with ionic bonds) with molecules of water, has a significant impact on the improvement of the sensitivity of the sensor in relation to volatile organic compounds when compared to the sensor without a filter.<\/jats:p>","DOI":"10.3390\/s16111881","type":"journal-article","created":{"date-parts":[[2016,11,9]],"date-time":"2016-11-09T10:09:39Z","timestamp":1478686179000},"page":"1881","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Impact of Sepiolite on Sensor Parameters during the Detection of Low Concentrations of Alcohols"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9246-0722","authenticated-orcid":false,"given":"Patrycja","family":"Suchorska-Wo\u017aniak","sequence":"first","affiliation":[{"name":"Faculty of Microsystem Electronics and Photonics, Wroc\u0142aw University of Science and Technology, Janiszewskiego 11\/17, Wroc\u0142aw 50-372, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8740-6817","authenticated-orcid":false,"given":"Olga","family":"Rac","sequence":"additional","affiliation":[{"name":"Faculty of Microsystem Electronics and Photonics, Wroc\u0142aw University of Science and Technology, Janiszewskiego 11\/17, Wroc\u0142aw 50-372, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7094-7003","authenticated-orcid":false,"given":"Marta","family":"Fiedot","sequence":"additional","affiliation":[{"name":"Faculty of Microsystem Electronics and Photonics, Wroc\u0142aw University of Science and Technology, Janiszewskiego 11\/17, Wroc\u0142aw 50-372, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5598-2983","authenticated-orcid":false,"given":"Helena","family":"Teterycz","sequence":"additional","affiliation":[{"name":"Faculty of Microsystem Electronics and Photonics, Wroc\u0142aw University of Science and Technology, Janiszewskiego 11\/17, Wroc\u0142aw 50-372, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,11,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"64","DOI":"10.1016\/S0040-6090(03)00510-8","article-title":"Mesoporous catalytic filters for semiconductor gas sensors","volume":"436","author":"Cabot","year":"2003","journal-title":"Thin Solid Films"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"400","DOI":"10.1016\/j.snb.2010.03.061","article-title":"Highly selective Pt\/SnO2 sensor to propane or methane in presence of CO and ethanol, using gold nanoparticles on Fe2O3 catalytic filter","volume":"147","author":"Oliaee","year":"2010","journal-title":"Sens.
