Abstract
A strain sensor includes a flexible substrate, a CNT film made of a plurality of CNT fibers aligned in an orientation direction, a pair of electrodes, and a protective coat. The electrodes are formed at the opposite ends of the CNT film in a perpendicular direction to the orientation direction of the CNT fibers. The protective coat protecting the CNT film is made of a resin, a water-based emulsion, or an oil-based emulsion. The protective coat is placed in contact with at least part of the CTN fibers on the surface of the CNT film. The strain sensor including the protective coat is able to prevent damage/breakage of the CNT film and to prevent foreign matters from entering into gaps between CNT fibers, thus improving durability in maintaining adequate sensing functionality.
