The study, “How a Raindrop Gets Shattered on Biological Surfaces,” published June 8 in the Proceedings of the National Academy of Sciences.
The research showed how microscale bumps, combined with a nanoscale layer of wax, shatter and spread these drops to protect fragile surfaces from physical damage and hypothermia risk.
There already exists a large market for products that use examples from nature – known as biomimicry – in their design: self-cleaning water-resistant sprays for clothes and shoes, and de-icing coatings on airplane wings. Findings from this study could lead to more such products in the future.
