The elastic modulus of metallic (Ag and Pb) nanowires and polymer (polypyrrole, PPy) nanotubes was measured using a novel method, resonant contact atomic force microscopy (resonant C-AFM). The cantilever vibration is excited with an electric field applied between the sample holder and the AFM head. The resonance frequency of the cantilever in contact with the sample shifts to higher values compared to the free resonance frequency. Its value depends on the stiffness of the tip-sample contact.
