A polymer composition is elastically deformable from a quiescent state and comprises at least one electrically conductive filler dispersed within and encapsulated by a non-conductive elastomer, the nature and concentration of the filler being such that the electrical resistivity of the composition is variable in response to distorsion forces down to a value substantially equal to that of the conductor bridges of the filler, the composition further comprising a modifier which, on release of the distorsion forces, accelerates the elastic return of the composition to its quiescent state.
