Study on Pressure and Temperature Characteristics of Sensitive Rubber Composite

Abstract:

In order to design and fabricate the flexible force sensor , we have researched the piezoresistivity of silicon rubber/ carbon black composites and given the academic calculation formula between pressure and electrical resistivity. The experiments illustrate that the homogenization of carbon black and the elastic modulus of composites can be improved effectively by dispersing nanosize silica filler and using organic solvent . As a result , the piezoresistivity of composites can be improved. Carbon black content of 10% with good pressure-sensitive conductive rubber, heat-sensitive in a certain pressure range is also good.Moreover , the fore - sensitive device fabricated by the composites is free from the limitation of the surface shape of the tested objects which can be widely applied to various squeeze stress measurement on any regular and unregular curve surfaces.
