Study on the Sensing Property of Carbon-Coated Filaments
This paper analyzes sensitivity, linearity, repeatability, strain relaxation of Carbon-coated Filaments (CCFS) in resistance tensile strain to evaluate CCFS’s sensing property. The results show that the relative resistance changes present two stages, change is stable in 0-6mm tensile range, while it amplitude increases in 6-15mm. CCFS’s linearity is better as number of filament increasing, while sensitivity is lower; if number is the same, CCFS sensitivity reduces as twist’s increasing. The 12F CCFS has poor repetitiveness and seriously flabby phenomenon when tensile change greatly.
