Compared with other types of fiber taper, the proposed WWFT has no difference in appearance with the single mode fiber and has ultralow insertion loss. The fabrication of WWFT also does not need the repeated cleaving and splicing process, and thereby could be rapidly embedded into the inline sensing fiber without splicing point, which greatly enhances the sensor solidity. Owing to the ultralow insertion loss (as low as 0.15 dB), the WWFT-based interferometer is further used for multiplexed curvature sensing. The results show that the different curvatures can be individually detected by the multiplexed interferometers. Furthermore, it also shows that diverse responses for the curvature changes exist in two orthogonal directions, and the corresponding sensitivities are determined to be 79.1\u00b0\/m\u22121 and \u201348.0\u00b0\/m\u22121 respectively. This feature can be potentially applied for vector curvature sensing.<\/jats:p>","DOI":"10.3390\/s21206782","type":"journal-article","created":{"date-parts":[[2021,10,13]],"date-time":"2021-10-13T21:48:39Z","timestamp":1634161719000},"page":"6782","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Multiplexed Weak Waist-Enlarged Fiber Taper Curvature Sensor and Its Rapid Inline Fabrication"],"prefix":"10.3390","volume":"21","author":[{"given":"Duo","family":"Yi","sequence":"first","affiliation":[{"name":"College of Physics and Optoelectronic Engineering, Shenzhen University, Shenzhen 518061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lina","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Physics and Optoelectronic Engineering, Shenzhen University, Shenzhen 518061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0019-3813","authenticated-orcid":false,"given":"Youfu","family":"Geng","sequence":"additional","affiliation":[{"name":"College of Physics and Optoelectronic Engineering, Shenzhen University, Shenzhen 518061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Du","sequence":"additional","affiliation":[{"name":"College of Physics and Optoelectronic Engineering, Shenzhen University, Shenzhen 518061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuejin","family":"Li","sequence":"additional","affiliation":[{"name":"School of Science and Engineering, Chinese University of Hong Kong, Shenzhen 518172, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xueming","family":"Hong","sequence":"additional","affiliation":[{"name":"College of Physics and Optoelectronic Engineering, Shenzhen University, Shenzhen 518061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104772","DOI":"10.1016\/j.nanoen.2020.104772","article-title":"A Soft Robotic Finger with Self-Powered Triboelectric Curvature Sensor Based on Multi-Material 3D Printing","volume":"73","author":"Zhu","year":"2020","journal-title":"Nano Energy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/j.engstruct.2019.03.068","article-title":"Damage Assessment of Shear Wall Components for RC Frame\u2013Shear Wall Buildings Using Story Curvature as Engineering Demand Parameter","volume":"189","author":"Xiong","year":"2019","journal-title":"Eng.
