Helmets are often called brain buckets, but the SMART is actually a cycling helmet that is pretty darn smart. While still under development via an Indiegogo project, its developers hope to create a cycling helmet with an integrated heart rate sensor.
Instead of wearing a heart rate monitor strap this system would provide real time, accurate monitoring via a sensor located in the helmet. This same type of sensors are currently used by fighter pilots and astronauts, and the developers have placed these in a Lazer Genesis helmet. The information gathered by the SMART sensor can be sent in real time to a mobile phone, sports watch or cycling computer via ANT+ and Bluetooth.
