  • Non-contact strain sensing of objects by use of single-walled carbon nanotubes
    Patent number: 9255853
    Abstract: In some embodiments, the present invention provides methods of detecting strain associated with an object by: (1) irradiating a composition that has been applied to the object, where the composition comprises semiconducting single-walled carbon nanotubes; (2) measuring an emission from the irradiated composition, where the emission comprises near infrared emission; and (3) correlating the near infrared emission to the presence or absence of strain associated with the object. In some embodiments, the aforementioned steps occur without physically contacting the object or the composition. In some embodiments, the aforementioned steps occur without utilizing Raman spectroscopy. Further embodiments of the present invention also include a step of applying the composition to the object.
