Abstract: The paper summarises the results of our investigations on the conductive silicone rubber as strain sensor. The dynamic behaviour of silicone rubber shows strong nonlinearity and because of the relaxation and creep the sensor can not be used for static measure. The greatest advantage of this material lies in its high elasticity. The commercial strain metallic or semiconductor gauges work in the range of 10-7<ε<10-3 . With the new silicone rubber sensor one can achieve elongations typically in the range of 10-2<ε<102 so this sensor offers new possibilities for the measure and control of high elasticity structures. The fatigue tests show that dynamic behaviour of the sensor silicone is stable.

Abstract: The paper presents the results of investigations made to clear how the different manufacturing technologies of silicone rubber structures affect the mechanical properties of the products. The problem is not obvious since there are numerous devices produced especially for the health care. We also controlled extreme high purity silicone rubbers and compared the results with data measured on simple industrial silicone rubbers. The aim was to see the difference between expensive medical materials and normal ones to simplify the fatigue tests and to decrease the costs of other mechanical investigations.
