Water droplets under freezing conditions do not spontaneously detach from surfaces as they do at room temperature due to stronger droplet-surface interaction and lack of an energy transformation pathway. Since accumulated droplets or ice have to be removed manually or with mechanical equipment, which is costly and inefficient, preventing droplet accretion on surfaces is both scientifically intriguing and practically important.
Nature-inspired design uses elastic pillars to eject freezing droplets, preventing ice buildup
