The development of sensors, wearable technology and materials, smart apparel and safer equipment can intelligently manage a person’s wellbeing and behavior in a personalized manner. At the University of Michigan, researchers are working to enhance sport technology in an effort to increase optimal performance and achievement of fitness and health goals. Their work has potential to prevent injury, identify better methods to evaluate potential for injury or to diagnose injury, and develop more informed approaches to optimally return the injured to activity.
Ellen Arruda, U-M professor of mechanical engineering, biomedical engineering and macromolecular science, is developing a prototype football helmet that she believes can better protect today’s athletes from concussion.
MITIGATIUM was designed using a composite structure that consists of lightweight elastic and viscoelastic components. The combination of a hard polymer shell and flexible plastic reduce most of the initial force and dissipate energy.
The National Institute of Standards and Technology (NIST) plans to run a series of tests on the MITIGATIUM design to determine if it performs better than current headgear. MITIGATIUM is one of five innovations being tested by NIST, and the winner will receive a $500,000 prize.
“Concussions occur when the brain moves relative to the skull, and that motion can be caused by force (how hard something hits something else) and impulse (how much energy is contained in the impact),” Arruda said. “Current helmets do a very good job of reducing force, and that’s important in preventing brain injuries and skull fractures, but they don’t do a very good job of mitigating impulse. That’s what our whole design strategy revolves around—mitigating force and dissipating energy. You really have to reduce both to prevent brain injury.”
