Football-helmet sensor warns of concussion risk via phone app

▤ Summary

As the Ravens take on the 49ers in New Orleans this weekend during the 47th Super Bowl, physicians will be on the lookout for more head injuries. Impakt Protectives Shockbox is a helmet g-force sensor that measures the impact a player sustains and gauges whether a medical assessment is in order. Priced at $149, the latest Shockbox sensor is a flexible rubber strip about 5 inches long, and it looks like a wristwatch. Up to 128 Shockboxes can be paired to a single phone, so coaches can use the app to track team hits over time. Shockbox follows other proposed helmet sensors such as the Shockometer, the Head Impact Telemetry System (HITS), and a skullcap from Reebok and startup MC10, but none has seen widespread acceptance.
