Mimicking tooth enamel to create the next super material

This is a perfect illustration of how abstracting the design principle from tooth enamel can lead to a novel material for plane hulls. Structural materials of most transportation devices have the same functional needs (e.g. strength, manage vibration, crack resistant) as tooth enamel, so abstracting the strategy helped a team at the University of Michigan emulate the tooth’s secret to success. According to this Gizmondo article, they used only using metal and polymer, rather than calcium and protein.
