I thought this was cool. It's a video that shows University of Michigan engineering and medical researchers testing concussion sensors by smashing helmets together over and over again. They're testing the new X2 Biosystems’ X-Patch against the Riddell HITS system that's been around for a few years. Very cool.
Thought it was timely given the big Superbowl matchup and head-slamming that's about to happen :-)
