BX-E
BX-E is an external decal that can be applied to any helmet. The impact-diverting decal was developed in 2013 at Simon Fraser University's Head Injury Prevention Lab.
Through standard oblique drop tests of American football, ice hockey, bicycle and motorcycle helmets using a standard human headform, it was found that reducing the frictional force can significantly reduce the rotational acceleration experienced by the headform. BX-E was first tested during the 2014 season of Simon Fraser University's Clan Football Team. "According to the coach (Jacques Chapdelaine), the number of concussions dropped from 14 cases in 2013 to only four cases in 2014 ... the decrease is also partly due to new tackling techniques taught by the team's coach."
