Armored skins must be hard to resist puncture and lacerations, yet compliant and light to allow for unimpeded movements. These conflicting requirements can be resolved by the segmentation of hard materials into scales of finite sizes, a common strategy in nature. In this work we used a combination of models and experiments to capture and optimize the design of segmented scales on soft substrates. We identified several unusual failure modes arising from the extreme contrast of stiffness between scales and the underlying substrates. Through mechanistic models and 3D printing of synthetic scaled skins, we showed how enriching the geometry of the scales can generate interlocking mechanisms between adjacent scales, resulting in improved stability and higher resistance to puncture. We now use these results to guide the design and optimization of synthetic bio-inspired flexible protective systems for a variety of applications, from industrial gloves to touch screens.
