The surface of the no core fiber (NCF) was coated by Pd\/WO3 film to detect the variation of hydrogen concentration. If the hydrogen concentration changes, the refractive index of the Pd\/WO3 film as well as the boundary condition for light propagating in the NCF will all be changed, which will then cause a shift into the resonant wavelength of interferometer. Therefore, the hydrogen concentration can be deduced by measuring the shift of the resonant wavelength. Experimental results demonstrated that this proposed sensor had a high detection sensitivity of 1.26857 nm\/%, with good linearity and high accuracy (maximum 0.0055% hydrogen volume error). Besides, it also possessed the advantages of simple structure, low cost, good stability, and repeatability.<\/jats:p>","DOI":"10.3390\/s17092144","type":"journal-article","created":{"date-parts":[[2017,9,19]],"date-time":"2017-09-19T07:12:50Z","timestamp":1505805170000},"page":"2144","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["A New Hydrogen Sensor Based on SNS Fiber Interferometer with Pd\/WO3 Coating"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7808-9189","authenticated-orcid":false,"given":"Jinxin","family":"Shao","sequence":"first","affiliation":[{"name":"College of Information Science and Engineering, Northeastern University, Shenyang 110819, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5397-8948","authenticated-orcid":false,"given":"Wenge","family":"Xie","sequence":"additional","affiliation":[{"name":"College of Information Science and Engineering, Northeastern University, Shenyang 110819, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0725-1534","authenticated-orcid":false,"given":"Xi","family":"Song","sequence":"additional","affiliation":[{"name":"College of Information Science and Engineering, Northeastern University, Shenyang 110819, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanan","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Information Science and Engineering, Northeastern University, Shenyang 110819, China"},{"name":"State Key Laboratory of Synthetical Automation for Process Industries, Shenyang 110819, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,9,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1901","DOI":"10.1126\/science.1109157","article-title":"Clearing the air and improving health with hydrogen fuel-cell vehicles","volume":"308","author":"Jacobson","year":"2005","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"204","DOI":"10.1016\/j.enpol.2011.09.046","article-title":"Assessing the potential of hybrid energy technology to reduce exhaust emissions from global shipping","volume":"40","author":"Dedes","year":"2012","journal-title":"Energy Policy"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1016\/S1364-0321(99)00011-8","article-title":"Renewable energy and sustainable development: A crucial review","volume":"4","author":"Dincer","year":"2000","journal-title":"Renew.
