MIT scientists make Flexible Superhero Body Armor inspired by … Lobsters



Imagine a highly sophisticated bulletproof vest that is robust as it is a flexible, shield consisting mainly of water but remains strong enough to prevent mechanical penetration.

Now imagine that this armor is not only strong but also soft and elastic, so much that the user is able to move parts of his body with ease, whether they swim in water, walk on the ground or rush to

The description may sound like a costume worn by a fictional hero in the DC Comics franchise, but it actually describes parts of a lobster exoskeleton. covering the joints and the abdomen of the animal – a material as hard as the industrial tire used for car tires and garden hoses – can guide the development of a new type of flexible armor pad for people to cover joints like knees and elbows

Researchers' findings appear in a recent edition of the journal "Acta Materialia ."

"We believe that this work can motivate the flexible bumper design," Ming Guo Assistant Professor and Arbeloff for Career Development at MIT's Machine Engineering Division told MIT News , noting that the lobster membrane has helped survive on Earth for more than 1

00 million years.

If you can make armor from these types of materials, you can freely move your joints and this will make you feel more comfortable.

Ballistic vests – commonly called "armor-vests" – are widely used by law enforcement officials and have received credits to save thousands of gun and gun ammunition officers, according to the National Institute of Justice, but they also come with challenges. Devlin Barrett announced in 2017, kevlar – tightly woven fibrous panels designed to stop bullet pistols – have a shelf life and usually last no more than five years.

Some studies have shown that bulletproof vests can also damage the shot and focus of the user, as well as increasing the "physiological cost of doing the job when is at work "at the same time According to the National Center for Biotechnology Information

researchers at the Massachusetts Institute of Technology think that lobsters can offer a solution to the problem that is torturing the most modern bulletproof vests: is Mobility Offers Bumper, The Less It Defends It

Guo told MIT News that the idea of ​​developing lighted-inspired bulletproof vests has arrived while he ate one and noticed that the transparent membrane of the belly of the animal is difficult to chew. Unlike the crust shell's outer shell, the soft tissues of the animal remain a mystery, he said.

After researchers began to dissect these tissues, they made a surprising discovery. Making significant cuts in the membrane did not affect the elasticity of the material.

Researchers have found that elasticity and strength are due to the unique structure of the membrane, which includes tens of thousands of layers that compare to plywood. Fibers in these layers help the material to distract energy when under stress, making it "tolerant", researchers write.

"The science of the soft membrane of natural lobsters sheds light on the design of synthetic soft but strong and robust materials for reliable use under extreme mechanical conditions, including a flexible armor that can provide complete body protection without sacrificing
