Firstly, POF, marketed and in development, have been compared in terms of the required mechanical properties for the insertion of the fiber directly into a knitted fabric on an industrial scale, i.e. elongation, bending rigidity, and minimum bending radius before plastic deformation. Secondly, the chosen optical fiber was inserted inside several types of knitted fabric and was shown to be sensitive to friction and compression. The knitted structure with the highest sensitivity has been chosen for sock prototype manufacturing. Finally, a feasibility study with an instrumented sock showed that it is possible to detect the different phases of walking in terms of compression and friction.<\/jats:p>","DOI":"10.3390\/s19133011","type":"journal-article","created":{"date-parts":[[2019,7,8]],"date-time":"2019-07-08T11:02:37Z","timestamp":1562583757000},"page":"3011","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["E-Knitted Textile with Polymer Optical Fibers for Friction and Pressure Monitoring in Socks"],"prefix":"10.3390","volume":"19","author":[{"given":"Claire","family":"Guignier","sequence":"first","affiliation":[{"name":"Laboratoire de Physique et M\u00e9canique Textiles, Ecole Nationale Sup\u00e9rieure d\u2019Ing\u00e9nieurs Sud-Alsace, Universit\u00e9 de Haute-Alsace, 11 rue Alfred Werner, F-68093 Mulhouse, France"},{"name":"Empa, Swiss Federal Laboratories for Materials Science and Technology, Laboratory for Biomimetic Membranes and Textiles, Lerchenfeldstrasse 5, CH-9014 St. Gallen, Switzerland"}]},{"given":"Brigitte","family":"Camillieri","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique et M\u00e9canique Textiles, Ecole Nationale Sup\u00e9rieure d\u2019Ing\u00e9nieurs Sud-Alsace, Universit\u00e9 de Haute-Alsace, 11 rue Alfred Werner, F-68093 Mulhouse, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5299-5885","authenticated-orcid":false,"given":"Michel","family":"Schmid","sequence":"additional","affiliation":[{"name":"Empa, Swiss Federal Laboratories for Materials Science and Technology, Laboratory for Biomimetic Membranes and Textiles, Lerchenfeldstrasse 5, CH-9014 St. Gallen, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0946-682X","authenticated-orcid":false,"given":"Ren\u00e9","family":"Rossi","sequence":"additional","affiliation":[{"name":"Empa, Swiss Federal Laboratories for Materials Science and Technology, Laboratory for Biomimetic Membranes and Textiles, Lerchenfeldstrasse 5, CH-9014 St. Gallen, Switzerland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5067-217X","authenticated-orcid":false,"given":"Marie-Ange","family":"Bueno","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique et M\u00e9canique Textiles, Ecole Nationale Sup\u00e9rieure d\u2019Ing\u00e9nieurs Sud-Alsace, Universit\u00e9 de Haute-Alsace, 11 rue Alfred Werner, F-68093 Mulhouse, France"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Tao, X.
