In this aspect, flexible thermoelectrics (FTE) such as wearable fabrics, smart biosensing, and biomedical electronics offer a variety of applications. Since the nanofibers are one of the important constructions of FTE, inorganic thermoelectric fibers are focused on here due to their excellent thermoelectric performance and acceptable flexibility. Additionally, measurement and microstructure characterizations for various thermoelectric fibers (Bi-Sb-Te, Ag2Te, PbTe, SnSe and NaCo2O4) made by different fabrication methods, such as electrospinning, two-step anodization process, solution-phase deposition method, focused ion beam, and self-heated 3\u03c9 method, are detailed. This review further illustrates that some techniques, such as thermal drawing method, result in high performance of fiber-based thermoelectric properties, which can emerge in wearable devices and smart electronics in the near future.<\/jats:p>","DOI":"10.3390\/s21103437","type":"journal-article","created":{"date-parts":[[2021,5,17]],"date-time":"2021-05-17T02:31:34Z","timestamp":1621218694000},"page":"3437","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Inorganic Thermoelectric Fibers: A Review of Materials, Fabrication Methods, and Applications"],"prefix":"10.3390","volume":"21","author":[{"given":"Jiwu","family":"Xin","sequence":"first","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore 639798, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdul","family":"Basit","sequence":"additional","affiliation":[{"name":"Department of Physics, National Changhua University of Education, Changhua City 50074, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sihui","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Materials Processing and Die and Mould Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylvain","family":"Danto","sequence":"additional","affiliation":[{"name":"National Centre for Scientific Research (CNRS), University of Bordeaux, F-33600 Pessac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3833-0414","authenticated-orcid":false,"given":"Swee Chuan","family":"Tjin","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore 639798, Singapore"},{"name":"The Photonics Institute, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore 639798, Singapore"},{"name":"The Photonics Institute, Nanyang Technological University, 50 Nanyang Avenue, Singapore 639798, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7399","DOI":"10.1021\/acs.chemrev.0c00026","article-title":"Advanced thermoelectric design: From materials and structures to devices","volume":"120","author":"Shi","year":"2020","journal-title":"Chem.
