Fog harvest processes on different surfaces. Fog harvest processes that were carried out on the (a) superhydrophobic surface with wedge-shaped superhydrophilic dimple array, (b) superhydrophobic surface with round superhydrophilic dimple array, (c) superhydrophobic surface with connected round superhydrophilic dimple array, (d) bare superhydrophobic surface and (e) bare superhydrophilic surface. Dimension of the substrates was 40 × 40 mm. Positions 1–12 marked by red arrows in (a–d) were some selected positions where the nucleated droplets were transported into the tracks. Dimensions of the patterns in (a–c) were illustrated in Fig. S2a–c, respectively in the Supplementary Information.
