We investigated resonance wavelength shifts in metasurface stickers under bending deformation. Stickers with square arrays of TiO2 nanoparticles and one dimensional grating structures were bent and their transmission spectra were measured. As the radius of curvature decreased, resonance peaks shifted to shorter wavelengths corresponding to a reduction in the period along the bending direction. Normalized comparisons revealed that the magnitude of the shift was nearly independent of the metasurface structure.
