The benefit of GMR grating sensors is the non-contact, easy optical read-out with large working distance, avoiding costly alignment and packaging procedures. The GMR gratings with resonance around 850\u2013900 nm are fabricated using electron beam lithography and replicated using a soft stamp based imprinting technique on 175    \u03bc   m-thick foils to make them suitable for optical strain sensing. For the strain measurements, foils are realized with both GMR gratings and waveguides with Bragg gratings. The latter are used as reference sensors and allow extracting the absolute strain sensitivity of the GMR sensor foils. Following this method, it is shown that GMR gratings have an absolute strain sensitivity of 1.02 \u00b1 0.05     pm \/ \u03bc \u03b5     at 870 nm.<\/jats:p>","DOI":"10.3390\/s20113221","type":"journal-article","created":{"date-parts":[[2020,6,9]],"date-time":"2020-06-09T05:16:14Z","timestamp":1591679774000},"page":"3221","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Imprinted Polymer-Based Guided Mode Resonance Grating Strain Sensors"],"prefix":"10.3390","volume":"20","author":[{"given":"Marie-Aline","family":"Mattelin","sequence":"first","affiliation":[{"name":"Center for Microsystems Technology (CMST), Ghent University and imec, 9052 Ghent, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3470-620X","authenticated-orcid":false,"given":"Jeroen","family":"Missinne","sequence":"additional","affiliation":[{"name":"Center for Microsystems Technology (CMST), Ghent University and imec, 9052 Ghent, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1815-6436","authenticated-orcid":false,"given":"Bert","family":"De Coensel","sequence":"additional","affiliation":[{"name":"WAVES Research Group, INTEC, Ghent University and imec, 9052 Ghent, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Geert","family":"Van Steenberge","sequence":"additional","affiliation":[{"name":"Center for Microsystems Technology (CMST), Ghent University and imec, 9052 Ghent, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Campanella, C.E., Cuccovillo, A., Campanella, C., Yurt, A., and Passaro, V.M.N.
