Abstract

In this study, carbon-nanotubes-based Al/CNT/Al displacement sensors were designed, fabricated by deposition of the carbon nanotubes on an adhesive elastic polymer tape, and placed in the elastic casing, and investigated. The diameter of multiwalled nanotubes varied between 10–30 nm. The thickness of the carbon nanotube layers in the samples was 300–430 μm. The interelectrode distance (length) and width of the surface-type samples were in the range of 4–6 mm and 3–4 mm, respectively. The DC resistance of the sensors from different batches was decreased on average by 3 times as the displacement was increased up to 900 μm. The resistance–displacement relationships were supported by simulation.
