Rectangular EpoCore negative resist strip waveguides are formed employing standard UV mask lithography. Highly persistent Bragg gratings are inscribed directly into the channel waveguides by permanently modifying the local refractive indices through a well-defined KrF excimer laser irradiated +1\/-1 order phase mask. The reproducible and vastly versatile sensing capabilities of this easy-to-apply optomechanical sensor pad are demonstrated in the form of an optical pickup for acoustic instruments, a broadband optical accelerometer, and a biomedical vital sign sensor monitoring both respiration and pulse at the same time.<\/jats:p>","DOI":"10.3390\/s19194101","type":"journal-article","created":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T03:26:32Z","timestamp":1569209192000},"page":"4101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Multipurpose Polymer Bragg Grating-Based Optomechanical Sensor Pad"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0390-7284","authenticated-orcid":false,"given":"Steffen","family":"Hessler","sequence":"first","affiliation":[{"name":"Applied Laser and Photonics Group, University of Applied Sciences Aschaffenburg, Wuerzburger Stra\u00dfe 45, 63743 Aschaffenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Bott","sequence":"additional","affiliation":[{"name":"Weber GmbH Pruefzentrum, Wailandtstra\u00dfe 6, 63741 Aschaffenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5344-5618","authenticated-orcid":false,"given":"Stefan","family":"Kefer","sequence":"additional","affiliation":[{"name":"Applied Laser and Photonics Group, University of Applied Sciences Aschaffenburg, Wuerzburger Stra\u00dfe 45, 63743 Aschaffenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6615-370X","authenticated-orcid":false,"given":"Bernhard","family":"Schmauss","sequence":"additional","affiliation":[{"name":"Institute of Microwaves and Photonics, University of Erlangen-Nuremberg, Cauerstra\u00dfe 9, 91054 Erlangen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ralf","family":"Hellmann","sequence":"additional","affiliation":[{"name":"Applied Laser and Photonics Group, University of Applied Sciences Aschaffenburg, Wuerzburger Stra\u00dfe 45, 63743 Aschaffenburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1016\/S0924-4247(99)00368-4","article-title":"Fiber optic sensor technology: An overview","volume":"82","author":"Grattan","year":"2000","journal-title":"Sens.
