Electronics based on nanomaterials (e.g. nanoparticles, nanotubes, nanowires, thin films) have been attracting interest recently due to their strain sensing characteristics. Strain sensors comprised of carbon nanotubes (CNTs) and silver nanowires, or graphene serve as good alternatives for developing new sensors because of their outstanding properties. Here, we report about thin films of single-walled carbon nanotubes (SWCNTs) which can be used as a key component of different electronic devices. The electrical properties of these devices can exhibit excellent characteristics compared to the traditional sensors due to a combination of high elastic moduli and outstanding electrical properties. The SWCNT films used in this study were obtained by aerosol synthesis and characterized by high structural quality.
