Geckos, spiders, flies and beetles can climb vertical walls and even adhere to ceilings. Nacre exhibits superior toughness compared to its mineral constituents. This talk will try to explore the design principles that enable the properties found in nature, reduce them to the simplest formulation possible without loosing the essence, and transfer them to potential technological structures. Fibrillar adhesive structures are investigated for optimal material (Young's modulus), size, aspect ratio and spacing. For brick and mortar structure, on the other hand, as found in nacre, a variation in building block thickness and aspect ratio is explored. Surprisingly, the parameters found in nature are very close to the theoretical optimum.
