Dr. David Camarillo is a bioengineering professor at Stanford University & a brain injury expert. His lab has designed a new very large helmet to greatly reduce the risk of brain injury. It provides more space & therefore more time for the head to slow down so that the brain is not bruised by hitting the inside of the skull.
It is now well accepted by scientists that multiple concussions can put a person at great risk & can lead to serious brain problems later in life such as Alzheimer’s. Therefore, even though the size of this helmet may look silly to us now, within a few years we may well see cyclists, motorcyclists and football players all wearing helmets like this to reduce their risk of a concussion.
This technology can potentially also be used for air bags to prevent head injuries in car accidents.
