Shockbox is a g-force sensor that can be attached to a helmet and aims to improve safety in sports. It sends an immediate alert to a smartphone if a player has experienced a head impact that could result in a concussion, so they can be told to stop playing and seek medical advice.

It is similar to Reebok’s concussion-detecting helmet, but the small rubber strip can fit into any helmet and could be used in football, hockey, lacrosse, and snow sports.

The sensor, which is priced at $149, measures g-force when a player is hit and sends a color-coded alert via Bluetooth. Hits over 50G generate an orange alert, while hits over 90G will send out a red alert.

CNET notes that an accompanying Android, iOS, and BlackBerry app interprets the data, and up to 128 Shockbox devices can be paired to a single phone. This would enable coaches to use the app to look out for their whole team and be alerted when a player has been hit too hard. You can check out a commercial for Shockbox below:
