The progress of textile-based sensor

Electronic textiles, also known as smart textiles or smart fabrics, are one of the most promising form factors that enable electronics to be embedded in themselves, offering exceptional physical flexibility and unique size that are unachieved by other techniques. The textile-based sensor has already been a prominent candidate for sensing platform since it can be lightweight, comfortable, as well as easily incorporated into modern garments in a breathable and conformable way. In this review article, we initially summarize the distinctive superiorities of textile-based sensors. For example, they are often used for monitoring purposes in the medical context. Besides, they can also protect the privacy of the user since it is unobtrusive and indistinguishable from the textile itself. Moreover, they can take the measurement at the place where the signal is strongest. Later, the characteristics and recent advances of optical, piezoresistive, piezoelectric, inductive, capacitive textile-based sensors are discussed based on the related working mechanisms and application. Additionally, a concise outline of the state-of-the-art achievements of textile-based sensors is demonstrated. Lastly, the present-day challenges in the development and forward-looking prospects are highlighted. These results shed light for more suitable choices drawn by scholars who intention to research textile sensor technology.
