In this paper, the characteristics of nano-SiO2 and mechanism of modification technology of nano-SiO2 are investigated. Through doping experiments for flexible tactile sensing material-conductive rubber, the effects of nano- SiO2 on the conductivity, resistance creep behavior and temperature stability of the conductive rubber are researched. Analyses are made on improving the linearity, hysteresis and repeatability of the tactile sensor. The performance comparison was carried out for different content filled nano-SiO2 and unfilled nano-SiO2. When the filled content mass percent of nano- SiO2 is 3% , better integrated performance of the tactile sensor was obtained. The resuits show that nano- SiO2 has good modification effect on flexible tactile sensor.
