Front Cover: The properties of elastomers are exploited to trigger wrinkling instabilities in curved shells. Each electrospun micro‐ or nanofiber consists of a soft core and a stiff outer half‐shell, which are length‐mismatched because of differential solvent de‐swelling. The fibers only wrinkle after attaining a well‐defined helical shape. A simple analytical model is proposed to find the curvature and wrinkle wavelength.
