University of Florida football helmet of the future uses fluid-filled reservoirs

GAINESVILLE, Fla. - Concussions and head injuries have become an important topic in the news.  The University of Florida is working to develop a football helmet to protect against a common cause of head injuries.

Sport-related head injuries are generally caused by direct impact from linear acceleration or forces caused by rotational acceleration.

About half of brain injuries are caused by rotational acceleration, yet most helmets are designed to protect against linear impact.

Engineers and researchers are developing a new layer for helmets that will absorb energy and protect against rotational acceleration. 

The added layer has fluid-filled reservoirs with a motion-activated thickening fluid to help absorb and transfer energy. 

The outer layer of the helmet can rotate over the fluid film depending on the impact and dissipate the energy before it is transferred to the brain.
