Inspired by the water‐collecting strategies of desert beetles and spider silk , a novel kind of surface with star‐shaped wettablity patterns has been developed. By combining both wettability and shape gradients, the as‐prepared surface has gained higher efficiency in water collection compared to circle‐shaped wettability patterns and uniformly superhydrophilic or superhydrophobic surfaces.
