单电极电致发光纤维的连续制备及其可视化液体传感应用
Continuous Preparation of Single-electrode Electroluminescent Fibers and Their Visual Liquid Sensing Applications
摘要
Abstract
The advent of flexible electronics,smart sensors,and intelligent wearables has catalyzed a burgeon-ing interest in flexible electroluminescent devices.These devices,particularly electroluminescent fibers,are dis-tinguished by their portability,malleability,and integrability into textiles,offering substantial promise for ad-vancements in visual sensing technology.However,due to their mostly dual-electrode structure and complex fabri-cation process,there are still shortcomings in terms of cost,device uniformity,sensitivity,and flexibility.This paper develops a single-electrode electroluminescent fiber and achieves continuous preparation of electrolumines-cent fibers through a simple,scalable,and low-cost manufacturing process.Electroluminescence is achieved through wireless driving.The single-electrode fiber receives energy from the wireless radio field and forms a closed loop with the wireless transmission source through the ground wire to the earth,thus eliminating the depen-dence on external power sources.The single-electrode electroluminescent fiber consists of a conductive layer,a dielectric layer,and a luminescent layer,with a luminescent wavelength of 456 nm.It has good mechanical per-formance,luminescent performance,and flexibility.We applied it to the visualization sensing of solutions,and its luminescent intensity can achieve a recognition degree of 0.001%(mass fraction)for sodium chloride concen-tration,demonstrating excellent sensitivity and significant implications for sweat detection and biology.We fur-ther weaved it into luminescent fabrics,which have comparable breathability and mechanical properties to ordi-nary commercial fabrics and can achieve visual sensing of different concentrations of sodium chloride.In the do-main of wearable technology,wirelessly driven single-electrode electroluminescent fibers have enormous potential to achieve visual display and communication functions.关键词
