The mantis shrimp has gained notoriety in recent years after being featured on popular internet sites such as YouTube or the webcomic, “The Oatmeal.” This week, however, scientists have released a study that suggests the mantis shrimp may soon become better known for the body armor – including a helmet – it inspires.
Although researchers at University of California, Riverside, Purdue University, and other research institutions first began discussing the design implications of the mantis shrimp’s club structure several years ago, the study published this week in the journal Advanced Materials examines the unique herringbone structure in the outer layer of the mantis shrimp’s famous punching club.
Despite its petite size (measuring no more than six inches from head to tail), the little creature is best known for its phenomenal strength. Mantis shrimp use little hammer-like claws called dactyl clubs to deliver blows that can shatter aquarium glass.
The unusual strength displayed by the mantis shrimp has attracted researchers who are interested in replicating the remarkably strong material in the shrimp’s dactyl club.
Scientists and engineers have been interested in the mantis shrimp’s natural engineering for some time. In 2012, researchers published a paper about the internal structure of the dactyl club. Just two years later, some of those same researchers published further research about the club’s structure and its applicability to material design.
In 2014, researchers suggested that the club’s spiral architecture could inform innovation in protective materials engineering.
“The more we learn about this tiny creature and its multi-layered structural designs,” co-author and UC Riverside professor David Kisailus said in a statement, “the more we realize how much it can help us as we design better planes, cars, sports equipment and armor.”
