"As nocturnal creatures, moths need to maximize how well they can see in the dark whilst remaining less visible to avoid predators. This ability to collect as much of the available light as possible and at the same time reflect as little as possible, has inspired Researchers at the Swiss Federal Laboratories for Materials Science and Technology (Empa) to design a new type of photoelectrochemical cell using relatively low cost materials."

A new model gives scientists guidelines to develop ‘smart’ composite materials with wrinkled microstructures.

In a recent paper published in Journal of Bionic Engineering, researchers from BERG-IBB studied the topography and wettability of the underside of English weed (Oxalis pes-caprae) leaves using epoxy replicas created via a two-step casting process. Leaves were found to be close to super hydrophobic due to the presence of a characteristic pattern of irregular 100 µm – 200 µm × 60 µm convex papillae. The water repellency properties of such microstructured surfaces may have important applications, including self-cleaning, anti-microbial and anti-fouling.
