Researchers at the University of Michigan have developed a new protective technology designed to mitigate damage from blasts and impacts. While blasts and impacts may not penetrate existing protective gear and armor, the resulting energy can still cause significant tissue or hardware damage, such as concussions suffered by helmet-wearing athletes or military personnel. Only some of that energy can be dissipated by existing protective layers such as foam.

Frequency tuning allows significant reduction of impact energy

By using a combination of material layers with particular ratios of material properties, the new technology can adjust the vibration of the impacting force to specific frequencies that achieve maximum dissipation. In standard configurations for military helmets, simulations have demonstrated up to 100% mitigation of impacting forces. This technology could help to greatly reduce the incidence of concussions and soft tissue damage suffered by athletes and soldiers.
