Electrically conductive polymer nanocomposites as deformation sensors

This work is related to in situ measurements of the a.c. electrical properties under large strain of composites strongly contrasted in relation to their electrical and mechanical properties. First, a RC type model has been developed to model the electrical properties of strongly heterogeneous material by the use of an improvement in the R and C models developed in the literature. The value for each resistance and capacitor is directly derived …
