How does a Nike fuelband work
The Nike Fuel Band works by measuring the amount of oxygen your body is consuming using what they call Oxygen Kinetics.
The Fuel Band then takes that information and creates a universal measurement which they call NikeFuel. This number, then, can be used to measure any type of activity be it weight training, running, boxing, making breakfast, or simply rocking your baby.
This means that no matter what type of physical activity you indulge in, anyone can use it, and with its digital display you can find out exactly how close you are to meeting your daily fitness goals.
The Nike Fuel Band made it into the Top 5 Gadgets of 2012 list, beaten out only by Apple's iPhone 5, which took 1st place in the list.
