Carbon black (CB) and Graphite (GP) were embedded in poly(styrene–ethylene/butylene–styrene) (SEBS) to form CB/SEBS and GP/SEBS composites. The electrical resistance was monitored in situ during tensile, compressive and dynamic mechanical tests, obtaining a correlation between the electrical response and strain. In the dynamic test the conductivity of the composites showed almost the same behavior than the elastic modulus, decreasing at deformations higher than 1%.
