The advantages of optical metrology with plastic optical fiber have attracted the attention of the scientific community, as they allow the development of low-cost or cost competitive systems compared with conventional technologies. In this paper, the current state of the art of plastic optical fiber technology will be reviewed, namely its main characteristics and sensing advantages. Several measurement techniques will be described, with a strong focus on interrogation approaches based on intensity variation in transmission and reflection. The potential applications involving structural health monitoring, medicine, environment and the biological and chemical area are also presented.<\/jats:p>","DOI":"10.3390\/s120912184","type":"journal-article","created":{"date-parts":[[2012,9,5]],"date-time":"2012-09-05T11:40:07Z","timestamp":1346845207000},"page":"12184-12207","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":321,"title":["Optical Sensors Based on Plastic Fibers"],"prefix":"10.3390","volume":"12","author":[{"given":"L\u00facia","family":"Bilro","sequence":"first","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es\u2014P\u00f3lo de Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"},{"name":"Polytechnic Institute of Viana do Castelo, Avenida do Atl\u00e2ntico, 4900-348 Viana do Castelo, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8176-7953","authenticated-orcid":false,"given":"N\u00e9lia","family":"Alberto","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es\u2014P\u00f3lo de Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"},{"name":"Centre for Mechanical Technology and Automation, Department of Mechanical Engineering, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6002-1060","authenticated-orcid":false,"given":"Jo\u00e3o L.","family":"Pinto","sequence":"additional","affiliation":[{"name":"Department of Physics & I3N, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rog\u00e9rio","family":"Nogueira","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es\u2014P\u00f3lo de Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2012,9,5]]},"reference":[{"key":"ref_1","unstructured":"Tricker, R.
