This increasing demand for these micrometric devices is attributed to their large dynamic range, high sensitivity, fast-response, compactness and robustness. Additionally, they can perform in-situ measurements remotely and in harsh environments. This paper presents an overview of optical microfibers, with a focus on their applications in temperature sensing. This review broadly divides microfiber-based temperature sensors into two categories: resonant and non-resonant microfiber sensors. While the former includes microfiber loop, knot and coil resonators, the latter comprises sensors based on functionally coated\/doped microfibers, microfiber couplers, optical gratings and interferometers. In the conclusions, a summary of reported performances is presented.<\/jats:p>","DOI":"10.3390\/s18020461","type":"journal-article","created":{"date-parts":[[2018,2,5]],"date-time":"2018-02-05T04:29:42Z","timestamp":1517804982000},"page":"461","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["A Review of Microfiber-Based Temperature Sensors"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1375-7830","authenticated-orcid":false,"given":"Wanvisa","family":"Talataisong","sequence":"first","affiliation":[{"name":"Optoelectronics Research Centre, University of Southampton, Southampton SO17 1BJ, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1186-2637","authenticated-orcid":false,"given":"Rand","family":"Ismaeel","sequence":"additional","affiliation":[{"name":"Optoelectronics Research Centre, University of Southampton, Southampton SO17 1BJ, UK"}]},{"given":"Gilberto","family":"Brambilla","sequence":"additional","affiliation":[{"name":"Optoelectronics Research Centre, University of Southampton, Southampton SO17 1BJ, UK"}]}],"member":"1968","published-online":{"date-parts":[[2018,2,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2258","DOI":"10.1364\/OPEX.12.002258","article-title":"Ultra-low-loss optical fiber nanotapers","volume":"12","author":"Brambilla","year":"2004","journal-title":"Opt.
