Elastic conductors made of ribbons of aligned carbon nanotubes embedded in a matrix of poly(dimethylsiloxane) exhibit a stabilized resistance after several cycles of stretching and releasing. The elastic conductors were prepared by drawing a ribbon of carbon nanotubes from an aligned array of carbon nanotubes and positioning on cured poly(dimethylsiloxane). After providing each end of the ribbon with an electrode, a film of uncured poly(dimethylsiloxane) was cast on the ribbon and electrodes. After curing the film an elastic conductor was produced. The electrical resistance of this elastic conductor became stable after a few cycles of stretching and releasing to strains up to 100%.
