As-spun fibers were characterized by TG\/DTA, Scanning Electron Microscopy and FT-IR spectroscopy analysis. X-ray diffraction and FT-IR spectroscopy analysis confirmed the formation of nickel manganite with a cubic spinel structure, while N2 physisorption at 77 K enabled determination of the BET specific surface area as 25.3 m2\/g and (BJH) mesopore volume as 21.5 m2\/g. The material constant (B) of the nanocrystalline nickel manganite fibers applied by drop-casting on test interdigitated electrodes on alumina substrate, dried at room temperature, was determined as 4379 K in the 20\u201350 \u00b0C temperature range and a temperature sensitivity of \u22124.95%\/K at room temperature (25 \u00b0C). The change of impedance with relative humidity was monitored at 25 and 50 \u00b0C for a relative humidity (RH) change of 40 to 90% in the 42 Hz\u03c01 MHz frequency range. At 100 Hz and 25 \u00b0C, the sensitivity of 327.36 \u00b1 80.12 k\u03a9\/%RH was determined, showing that nickel manganite obtained by electrospinning has potential as a multifunctional material for combined humidity and temperature sensing.<\/jats:p>","DOI":"10.3390\/s21134357","type":"journal-article","created":{"date-parts":[[2021,6,25]],"date-time":"2021-06-25T11:07:40Z","timestamp":1624619260000},"page":"4357","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Electrospun Nickel Manganite (NiMn2O4) Nanocrystalline Fibers for Humidity and Temperature Sensing"],"prefix":"10.3390","volume":"21","author":[{"given":"Milena P.","family":"Dojcinovic","sequence":"first","affiliation":[{"name":"Institute for Multidisciplinary Research, University of Belgrade, 11030 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7817-8648","authenticated-orcid":false,"given":"Zorka Z.","family":"Vasiljevic","sequence":"additional","affiliation":[{"name":"Institute for Multidisciplinary Research, University of Belgrade, 11030 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jugoslav B.","family":"Krstic","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Department of Catalysis and Chemical Engineering, Technology and Metallurgy, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jelena D.","family":"Vujancevic","sequence":"additional","affiliation":[{"name":"Institute of Technical Sciences of SASA, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Smilja","family":"Markovic","sequence":"additional","affiliation":[{"name":"Institute of Technical Sciences of SASA, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nenad B.","family":"Tadic","sequence":"additional","affiliation":[{"name":"Faculty of Physics, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5035-0170","authenticated-orcid":false,"given":"Maria Vesna","family":"Nikolic","sequence":"additional","affiliation":[{"name":"Institute for Multidisciplinary Research, University of Belgrade, 11030 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7881","DOI":"10.3390\/s140507881","article-title":"Humidity sensors principle, mechanism and fabrication technologies: A comprehensive review","volume":"14","author":"Faharani","year":"2014","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3593","DOI":"10.1021\/acsaelm.0c00660","article-title":"Printed, fully metal oxide, capacitive humidity sensors using conductive indium tin oxide inks","volume":"2","author":"McGhee","year":"2020","journal-title":"ACS Appl.
