Effect of Carbon Black Concentration on the Electrical Behavior of Force Sensing Resistor Composites

[摘要] The electrical DC conduction behaviour of force sensing resistors composites based on carbon black and poly(ethyl acrylate/methyl acrylate) (50/50) is presented. The carbon black concentration used in the present communication were 5, 10, 20, 25, and 30 % wt. It was found that the conductivity behaviour of the material is fully explained with the percolation model, up to 25 % of CB concentration. There exist a correlation between the external pressure applied to the composite and the percolation state; the higher the pressure the better the percolation state.
