Fig. 3. (a) Uniform, angular-independent structural colour observed upon finger (un)bending (T = 33 °C). (b) Photographs of the photonic e-skin (T = 33 °C) displaying a constant reflective colour upon stretching (ε = 0–1) and stress release (ε(rel) = 0). (c) POM images of the flexible PDCLC/AgNW film upon stretching and stress release, presenting a reversible spherical-to-oblate droplet deformation (scale bar = 50 μm).
