Used as a transmit-and-receive sensor, it was placed at a 2 mm distance from organic material test samples (pork fillet samples) which were previously burned on their surface in various heating conditions involving different temperatures, durations, and procedures. Data extracted from the sensor by means of a distant monitoring coil were found to clearly correlate with the depth of burn observed in the tissue samples (up to 40% sensor output changes for a 7 mm burn depth) and with the heating conditions (around 5% sensor output changes observed in samples burned with identical heating procedures but at two different temperatures\u201475 \u00b0C and 150 \u00b0C\u2014and around 40% sensor output changes observed between samples heated at the same temperature but with different heating procedures). These results open the way for the development of easy-to-implement assessment and monitoring techniques for burns, e.g., integrated in wearable medical dressing-like monitoring devices.<\/jats:p>","DOI":"10.3390\/s19051220","type":"journal-article","created":{"date-parts":[[2019,3,12]],"date-time":"2019-03-12T03:49:31Z","timestamp":1552362571000},"page":"1220","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Non-Contact Radiofrequency Inductive Sensor for the Dielectric Characterization of Burn Depth in Organic Tissues"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8343-9662","authenticated-orcid":false,"given":"Thi Hong Nhung","family":"Dinh","sequence":"first","affiliation":[{"name":"Centre for Nanoscience and Nanotechnology (C2N), CNRS, University Paris-Sud, Universit\u00e9 Paris-Saclay, C2N-Orsay, 91405 Orsay, CEDEX, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"St\u00e9phane","family":"Serfaty","sequence":"additional","affiliation":[{"name":"Systems and Applications of Information and Energy Technologies (SATIE), CNRS, Universit\u00e9 de Cergy-Pontoise, 95000 Cergy-Pontoise, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6121-7188","authenticated-orcid":false,"given":"Pierre-Yves","family":"Joubert","sequence":"additional","affiliation":[{"name":"Centre for Nanoscience and Nanotechnology (C2N), CNRS, University Paris-Sud, Universit\u00e9 Paris-Saclay, C2N-Orsay, 91405 Orsay, CEDEX, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1695","DOI":"10.1016\/j.burns.2015.06.023","article-title":"A comparison of non-invasive imaging modalities: Infrared thermography, spectrophotometric intracutaneous analysis and laser Doppler imaging for the assessment of adult burns","volume":"41","author":"Collier","year":"2015","journal-title":"Burns"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"178","DOI":"10.1097\/00129334-200307000-00010","article-title":"Partial-Thickness Burns: Identification and Management","volume":"16","author":"Johnson","year":"2003","journal-title":"Adv.
