  • Highly compliant resonant diffraction gratings, and methods and use thereof
    Patent number: 9234991
    Abstract: Highly-compliant polymer-based resonant diffraction gratings, and methods of use thereof, are provided. In one illustrative embodiment, an amount of pressure applied to a grating surface may be determined by straining a grating, adapted to move into a plurality of pitches, to an applied pitch in the plurality of pitches in response to an application of strain onto a surface adjacent the grating. Electromagnetic radiation comprising a plurality of wavelengths may be applied to the grating, and a resonance wavelength, in the plurality of wavelengths, may be identified while the strain is applied to the grating. The amount of strain applied to the grating surface may then be determined based on the resonant wavelength.
    Type: Grant
