Research on Nano-SiO2/Carbon Black Composite for Flexible Tactile Sensing

In this paper, aiming at pressure sensitive conductive rubber materials based on flexible tactile sensing, studying the influence of adding nano-SiO₂ materials on the electrical and mechanical performances. Analyses are made on the phenomenon produced by filling nano-SiO₂ with different contents through experiments, researching the micro and macro mechanism of nano-SiO₂ modification theoretically. The results showed that the combination of suitable nano-SiO₂ and carbon black can effectively increase the conductivity of composites, and improve piezoresistive properties and stability of composites. It can provide pressure sensitive conductive rubber with high conductivity and fine mechanical properties for flexible tactile sensors.
