Abstract
The present invention provides a method and system for monitoring external excitation on a surface using nanocomposite paint. The method comprises applying the nanocomposite paint on the surface, wherein the nanocomposite paint comprises a mixture of a plurality of carbon nanotubes and an epoxy resin along with a plurality of electrically conductive patterned electrodes. The electrical properties of the nanocomposite paint changes in response to the external excitation of the surface. The change in the electrical properties of the nanocomposite is measured by a measuring instrument, wherein the change in the electrical properties of the nanocomposite paint is directly proportional to the external excitation experienced by the surface.
