Addressing the issues of poor flexibility and low comfort associated with traditional rigid conductive materials,as well as the inadequate air and moisture permeability of existing ionic conductive materials typically found in the form of films or blocks,a one-dimensional ionic sensing fiber produced through a one-step wet spinning process was presented,and its physical and sensing properties were investigated to delineate its future development potential.The results indicate that ion sensing fibers display high sensitivity(GF=2.01)and can precisely monitor small strains(around 0.5%),showcasing a wide strain monitoring range.With a response time of less than 50 ms,closely mirroring the response time of human skin,the fibers are well-suited for monitoring human motion signals.Additionally,the fibers exhibit outstanding cyclic durability,preserving stable resistance signal changes even after 10 000 stretching cycles.Furthermore,they possess humidity sensing capabilities,delivering timely and accurate signal feedback in response to variations in environmental humidity.The ionic sensing fiber is easily prepared and holds significant potential for large-scale industrialization,making it highly promising in the realms of intelligent health monitoring,sports training and optimization,intelligent human-computer interaction and more.
