The Effect of Particles on Electrolytically Polymerized Thin Natural MCF Rubber for Soft Sensors Installed in Artificial Skin

The aim of this study is to investigate the effect of particles as filler in soft rubber sensors installed in artificial skin. We examine sensors made of natural rubber (NR-latex) that include magnetic particles of Ni and Fe(3)O(4) using magnetic compound fluid (MCF). The 1-mm thickness of the electrolytically polymerized MCF rubber makes production of comparatively thin rubber sensors feasible. We first investigate the effect of magnetic particles Ni and Fe(3)O(4) on the curing of MCF rubber. Next, in order to adjust the electric properties of the MCF rubber, we adopt Al(2)O(3) dielectric particles. We investigate the effect of Al(2)O(3) particles on changes in electric current, voltage and temperature of electrolytically polymerized MCF rubber liquid, and on the electric properties under the application of normal and shear forces. By adjusting the ratio of Ni, Fe(3)O(4), Al(2)O(3) and water in MCF rubber with Al(2)O(3), it is possible to change the electric properties.
