The sensor\u2019s pressure sensitivity was measured to be 14 times higher than bare FBG when tested inside stacks of ultra-high-molecular-weight polyethylene (UHMWPE) composite fabric. The sensitivity can be further improved 6-fold through the Vernier effect. Its tiny sensing length (hundreds of microns) and uniform outer diameter (125 \u00b5m) make it a suitable candidate for real-time point pressure monitoring under harsh environments with limited space, such as in composite-forming procedures.<\/jats:p>","DOI":"10.3390\/s22207850","type":"journal-article","created":{"date-parts":[[2022,10,17]],"date-time":"2022-10-17T03:43:58Z","timestamp":1665978238000},"page":"7850","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Fiber Lateral Pressure Sensor Based on Vernier\u2013 Effect Improved Fabry\u2013Perot Interferometer"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6523-8114","authenticated-orcid":false,"given":"Xu","family":"Guo","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Massachusetts Lowell, Lowell, MA 01854, USA"}]},{"given":"Rui","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Massachusetts Lowell, Lowell, MA 01854, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9265-2556","authenticated-orcid":false,"given":"Jingcheng","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Nano Engineering, University of California, 9500 Gilman Drive, San Diego, CA 92092, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5941-5719","authenticated-orcid":false,"given":"Andres","family":"Biondi","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Massachusetts Lowell, Lowell, MA 01854, USA"}]},{"given":"Lidan","family":"Cao","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Massachusetts Lowell, Lowell, MA 01854, USA"}]},{"given":"Xingwei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Massachusetts Lowell, Lowell, MA 01854, USA"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,16]]},"reference":[{"key":"ref_1","unstructured":"Chung, D.D.
