The polymer electrolyte is based on the ionic liquid 1-butyl 3-methylimidazolium bis(trifluoromethylsulfonyl)imide [BMIM][NTf2] immobilized in a poly(vinylidene fluoride) matrix. An innovative aerosol-jet printing technique was used to deposit the gold working electrode (WE) on the solid polymer electrolyte layer to make a unique electrochemical active SPE\/WE interface. The analyte, gaseous ethylene, was detected by oxidation at 800 mV vs. the platinum pseudoreference electrode. The sensor parameters such as sensitivity, response\/recovery time, repeatability, hysteresis, and limits of detection and quantification were determined and their relation to the morphology and microstructure of the SPE\/WE interface examined. The use of additive printing techniques for sensor preparation demonstrates the potential of polymer electrolytes with respect to the mass production of printed electrochemical gas sensors.<\/jats:p>","DOI":"10.3390\/s21030711","type":"journal-article","created":{"date-parts":[[2021,1,21]],"date-time":"2021-01-21T09:49:21Z","timestamp":1611222561000},"page":"711","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["An Electrochemical Amperometric Ethylene Sensor with Solid Polymer Electrolyte Based on Ionic Liquid"],"prefix":"10.3390","volume":"21","author":[{"given":"Petr","family":"Kubersk\u00fd","sequence":"first","affiliation":[{"name":"Research and Innovation Centre for Electrical Engineering (RICE), Faculty of Electrical Engineering, University of West Bohemia, Univerzitn\u00ed 8, 306 14 Plze\u0148, Czech Republic"}]},{"given":"Ji\u0159\u00ed","family":"Navr\u00e1til","sequence":"additional","affiliation":[{"name":"Research and Innovation Centre for Electrical Engineering (RICE), Faculty of Electrical Engineering, University of West Bohemia, Univerzitn\u00ed 8, 306 14 Plze\u0148, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3943-8643","authenticated-orcid":false,"given":"Tom\u00e1\u0161","family":"Syrov\u00fd","sequence":"additional","affiliation":[{"name":"Department of Graphic Arts and Photophysics, Faculty of Chemical Technology, University of Pardubice, 532 10 Pardubice, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2454-7951","authenticated-orcid":false,"given":"Petr","family":"Sedl\u00e1k","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Communications, Brno University of Technology, Technick\u00e1 10, 616 00 Brno, Czech Republic"}]},{"given":"Stanislav","family":"Ne\u0161p\u016frek","sequence":"additional","affiliation":[{"name":"Research and Innovation Centre for Electrical Engineering (RICE), Faculty of Electrical Engineering, University of West Bohemia, Univerzitn\u00ed 8, 306 14 Plze\u0148, Czech Republic"}]},{"given":"Ale\u0161","family":"Ham\u00e1\u010dek","sequence":"additional","affiliation":[{"name":"Research and Innovation Centre for Electrical Engineering (RICE), Faculty of Electrical Engineering, University of West Bohemia, Univerzitn\u00ed 8, 306 14 Plze\u0148, Czech Republic"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1016\/S0925-5214(98)00091-X","article-title":"Effect of ethylene on quality of fresh fruits and vegetables","volume":"15","author":"Saltveit","year":"1999","journal-title":"Postharvest Biol.
