The material was prepared by solid state reaction from commercial hematite and strontium carbonate heat treated at 900 \u00b0C. X-Ray diffraction, scanning electron microscopy and mercury intrusion porosimetry were used for microstructural characterization of the synthesized powder. Sensors were then prepared by uniaxially pressing and by screen-printing, on an alumina substrate, the prepared powder and subsequent firing in the 800\u20131,000 \u00b0C range. These sensors were first tested in a laboratory apparatus under humid air and then in an homogenized soil and finally in field. The results evidenced that the screen printed film was able to give a response for a soil matric potential from about 570 kPa, that is to say well below the wilting point in the used soil.<\/jats:p>","DOI":"10.3390\/s130912070","type":"journal-article","created":{"date-parts":[[2013,9,11]],"date-time":"2013-09-11T03:51:10Z","timestamp":1378871470000},"page":"12070-12092","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Strontium-Doped Hematite as a Possible Humidity Sensing Material for Soil Water Content Determination"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2419-4383","authenticated-orcid":false,"given":"Jean-Marc","family":"Tulliani","sequence":"first","affiliation":[{"name":"Department of Applied Science and Technology, Politecnico di Torino, C.so Duca degli Abruzzi 24, 10129 Torino, Italy"}]},{"given":"Chiara","family":"Baroni","sequence":"additional","affiliation":[{"name":"Department of Applied Science and Technology, Politecnico di Torino, C.so Duca degli Abruzzi 24, 10129 Torino, Italy"}]},{"given":"Laura","family":"Zavattaro","sequence":"additional","affiliation":[{"name":"Department of Agricultural, Forest and Food Sciences, Universit\u00e0 di Torino,  Via Leonardo da Vinci, 44, 10095 Grugliasco, Italy"}]},{"given":"Carlo","family":"Grignani","sequence":"additional","affiliation":[{"name":"Department of Agricultural, Forest and Food Sciences, Universit\u00e0 di Torino,  Via Leonardo da Vinci, 44, 10095 Grugliasco, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2013,9,10]]},"reference":[{"key":"ref_1","unstructured":"WWAP (World Water Assessment Programme) Available online: http:\/\/www.unesco.org\/new\/en\/natural-sciences\/environment\/water\/wwap\/wwdr\/wwdr4\u20132012\/."},{"key":"ref_2","unstructured":"WWAP (World Water Assessment Programme) Available online: http:\/\/www.unesco.org\/new\/en\/natural-sciences\/environment\/water\/wwap\/wwdr\/wwdr4\u20132012."},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Warrick, A.W.
