68 reviewsBalancing protection with mobility is a tradeoff all levels of the food chain have
made in evolutionary development. The ability to withstand threats allows for longer
life, as long as it does not degrade the ability to hunt and evade. The same can be said
for modern engineered protection. Analogies can be drawn between common forms of
man-made personal protection and the soft-body protecting structures seen in nature.
However, nature has figured out how to balance encumberment with protection
through the evolution of compound armors in a way that humans have yet to do in a
relevant way. Fish-skin presents a novel protective structure that accomplishes this
goal through the use of imbricated stiff scales embedded in soft dermal tissue. By
modulating basic properties of the assembly, scale interactions can be enhanced to
provide force dissipation and energy absorption.
