Reebok Checklight

Concussions — and the long-term brain damage that may result — are now a major consideration in many impact sports. Reebok Checklight ($150), which won a best of innovations award at CES 2014, is a flexible, breathable cap that detects how serious those injuries are when they happen.

A small display on the back of the neck blinks yellow when Checklight receives a moderate impact, and blinks red when the impact is severe. Sensors in Checklight also log the number of impacts received as well as the measurement of impact force.
