The micro bubble is fabricated at the fiber tip by splicing a glass tube to a single mode fiber (SMF) and then the glass tube is filled with gas in order to expand and form a micro bubble. The sensitivity of the strain sensor with a cavity length of about 155 \u03bcm and a bubble wall thickness of about 6 \u03bcm was measured to be up to 8.14 pm\/\u03bc\u03f5.<\/jats:p>","DOI":"10.3390\/s17030555","type":"journal-article","created":{"date-parts":[[2017,3,9]],"date-time":"2017-03-09T11:12:17Z","timestamp":1489057937000},"page":"555","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["A Micro Bubble Structure Based Fabry\u2013Perot Optical Fiber Strain Sensor with High Sensitivity and  Low-Cost Characteristics"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8460-7261","authenticated-orcid":false,"given":"Lu","family":"Yan","sequence":"first","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"},{"name":"Engineering Technology Research Center of Shanxi Province for Opto-electric Information and Instrument, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiguo","family":"Gui","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guanjun","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"},{"name":"Engineering Technology Research Center of Shanxi Province for Opto-electric Information and Instrument, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongquan","family":"An","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"},{"name":"Engineering Technology Research Center of Shanxi Province for Opto-electric Information and Instrument, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinyu","family":"Gu","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"},{"name":"Engineering Technology Research Center of Shanxi Province for Opto-electric Information and Instrument, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meiqin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"},{"name":"Engineering Technology Research Center of Shanxi Province for Opto-electric Information and Instrument, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinglin","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"},{"name":"Engineering Technology Research Center of Shanxi Province for Opto-electric Information and Instrument, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhibin","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"},{"name":"Engineering Technology Research Center of Shanxi Province for Opto-electric Information and Instrument, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Information and Communication Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4547-0992","authenticated-orcid":false,"given":"Pinggang","family":"Jia","sequence":"additional","affiliation":[{"name":"School of Instrument and Electronics, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,3,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1917","DOI":"10.1140\/epjst\/e2014-02236-5","article-title":"Hollow core, whispering gallery resonator sensors","volume":"223","author":"Ward","year":"2014","journal-title":"Eur.
