Abstract

Continuous preparation of sensing fibers that respond to multiple stimuli is of great significance to the development of smart textile and clothing. However, in most cases, the production of sensing fibers is restricted to laboratory scale by factors of equipment and technology, thus it is still challenging to achieve industrial-scale fibers. In this study, continuous preparation of dual-responsive sensing fibers (DRSF) by a set of process designs with custom-built equipment, which consists of core fibers, functional layers, parallel electrodes and protective layers are reported. Combining vanadium pentoxide (V₂O₅) nanobelts with a unique device design, DRSFs exhibited a significant electrical output when stimulated by heat or blue light (460 nm), where the factors of the aspect ratio of one-dimensional nanostructures have also been explored. Furthermore, proof-of-concept electronic textiles with DRSFs woven into fabric were demonstrated.
