Flexible textile‐based sensors are versatile alternatives that can be comfortably worn and can detect a broad range of body and environment temperatures. Furthermore, they are becoming more essential due to the recent rise in the use of wearable customized gadgets, wearable clothing, sports, medical and soft robotics. Typically made from rigid materials like metals or semiconductors, traditional temperature sensors are heavy, inflexible, and difficult to wear since they can only endure very slight variations in their physical shape to be placed on any irregularly shaped object. In this review, we discuss developments in textile temperature sensors with a focus on their performance, fabrication techniques, advances in various materials, and applications, such as wearable monitoring and sports. Moreover, an in‐depth analysis of different performance parameters has also been presented. Lastly, in order to provide useful guidance and directions for future study, we conclude by outlining the current limitations of this field, and future recommendations for the scientific community to further explore other facets of textile temperature devices.This article is protected by copyright.

This work involved the synthesis of compositions of Ba0.95Ca0.05SnxTi1-xO3 (BCST) with varying amounts of Sn dopant (x = 0, 0.02, 0.04, 0.06, 0.08, and 0.1). A standard solid-state reaction approach was used to create all of the ceramic compounds. Each BCST composite’s microstructure, sintering, morphology, density, optical, and electrical characteristics were carefully examined, and the dielectric performance was optimized. In comparison to the unmodified composite, introducing varied amounts of Sn material into the BCST compound changed the crystal lattice vibrations and functional group locations. This result indicates that there are some variations in unit cell size, revealing that Sn+4 ions diffused effectively inside the lattice structure to produce BSCT composites. Further, SEM micrographs indicated proportionate changes in the homogenous structure and irregular forms as Sn concentration increased, as well as some variation in average grain size. As a consequence, by adding 0.08 mol% of Sn dopant, the crystallite size and average grain size were adjusted to 45.69 nm and 0.66 µm, respectively. Meanwhile, the 0.08-Sn specimen displayed a dielectric constant (Ɛ) with an optimum value of 5557 and a relative decrease in the Curie-Weiss constant. These results are attributed to the existence of various concentrations of Sn ions at the Ti-site of the BCT, which resulted in a compositionally disordered state. This disordered condition is essential for the production of dielectric compounds. Therefore, it is evident that modifying the amount of Sn doping added significantly enhanced the dielectric characteristics of the BCST composites created in this work. However, excessive Sn doping reduces the dielectric properties due to a reduction in tetragonal phase and an increase of disorders and charge fluctuations. Graphical Abstract
