Abstract:Stenocara beetles in the Namib Desert collect drinking water from the air on their backs. Water extraction from air(WEA)is an effective solution for water shortage, but the low water collection rate is a restriction to its wide application. Based on the analysis of the present WEA technology, the conclusion that the application of the beetle's bionic surface to WEA may increase the water collection rate is drawn in the paper. This provides new ideas for the WEA technology and might become the basis for the large-scale artificial schemes to gathering water from the air.
