The UFBG array interrogation principle is time division multiplex technology with two semiconductor optical amplifiers as timing units. Experimental results showed that the performance of the proposed UFBG system is almost equal to that of traditional FBG, while the UFBG array system has obvious superiority with potential multiplexing ability for multi-point and multi-parameter measurement. The system experimented on a 144 UFBG array with the reflectivity of UFBG ~0.04% for the four target parameters: hydrogen, humidity, temperature and salinity. Moreover, a uniform solution was customized to divide the cross-sensitivity between temperature and other target parameters. It is expected that this scheme will be capable of handling thousands of multi-parameter sensors in a single fiber.<\/jats:p>","DOI":"10.3390\/s17071509","type":"journal-article","created":{"date-parts":[[2017,6,27]],"date-time":"2017-06-27T02:58:05Z","timestamp":1498532285000},"page":"1509","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Ultra-Weak Fiber Bragg Grating Sensing Network Coated with Sensitive Material for Multi-Parameter Measurements"],"prefix":"10.3390","volume":"17","author":[{"given":"Wei","family":"Bai","sequence":"first","affiliation":[{"name":"National Engineering Laboratory for Fiber Optic Sensing Technologies, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minghong","family":"Yang","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Fiber Optic Sensing Technologies, Wuhan University of Technology, Wuhan 430070, China"},{"name":"Key Laboratory of Fiber Optic Sensing Technology and Information Processing, Ministry of Education, Wuhan, 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chenyuan","family":"Hu","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Fiber Optic Sensing Technologies, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jixiang","family":"Dai","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Fiber Optic Sensing Technologies, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuexiang","family":"Zhong","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Fiber Optic Sensing Technologies, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuai","family":"Huang","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Fiber Optic Sensing Technologies, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaopeng","family":"Wang","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Fiber Optic Sensing Technologies, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26","DOI":"10.1007\/s13320-015-0298-0","article-title":"Huge Capacity Fiber-Optic Sensing Network Based on Ultra-Weak Draw Tower Gratings","volume":"6","author":"Yang","year":"2016","journal-title":"Photonic Sens."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1406","DOI":"10.1109\/JLT.2014.2305714","article-title":"A Novel Interrogation System for Large Scale Sensing Network with Identical Ultra-Weak Fiber Bragg Gratings","volume":"32","author":"Hu","year":"2014","journal-title":"J.
