A strengthening method, nanohole strengthening, is proposed by mimicking the surface nanostructures on Cryptotympana takasagona Kato cicada's wing. Nanohole plates maintain the Young's modulus and the characteristics of brittle material because only surface morphology is modified. The nanoholes patterned on the region of tensile bending stress dominate the failure behavior and determine the bending stress at rupture. The bending stress at rupture of nanohole plates is 6 times larger than that of polished plates. The dynamic response of nanohole plates with the dimensions of 40 mm × 10 mm × 0.1 mm sustains the flapping frequency of 40 Hz and the displacement of 2 cm without failure behavior, performing the remarkable deflection in vibration environment.
