Abstract

In the research of 2D flexible tactile sensor matrix, pressure-sensitive conductive rubber was developed and tested in which carbon black was used as its conductive phase and silicon rubber as its matrix layer. Experiments were undertaken and the resultant data were used for its piezoresistive characteristics investigation for two kinds of electrode connection configurations, the surface directive connection and embedded connection. It is found that due to the rather strong nonlinearity of the piezoresistive characteristic curves obtained, a higher correlation relationship can be obtained by means of quadratic polynomial fitting. It also showed that the embedded electrode assembling has higher fitting accuracy while the surface directive connection has better mechanical sensitivity.
