Optimizing the strain-sensing property of cementbased composite based on a piezoresisitivity model
This paper indicated that aligning conductive filler in the composite was an effective approach to enhance the sensitivity and measuring range of the composite.Also,the dependence of the strain gauge factor of the composite on the Poisson ratio decreased upon the aligning level of the conductive filler till vanished for a perfect aligning.The measuring rang of the conductive composite increased upon the volume concentration of conductive filler.However,an adverse effect accompanying with this benefit the piezoresistivity was the decrease in strain gauge factor.Therefore,the volume concentration and aligning level of the conductive filler should be optimized upon the requirement on the piezoresistivity.
