Highly elastic and electrically conductive composite sheets are prepared by infiltration of MWNT forests with polyurethane binder. After initial pretreatment, the composite provides highly reproducible changes in resistivity at elongations up to 40%. Almost no degradation in electrical properties and a linear dependence of resistivity on strain is observed for strains in 10%–20% range.
