WearTec

If you are a runner, chances are that you have seen, or in fact are using, one of these heart monitors that strap to the chest and have a little wireless watch that shows you your heart rate.
Polar Electro and Adidas have taken this concept one step further by integrating sensors to monitor speed, heart rate and distance into shoes and clothing.

“How does it work? Special fibers bonded onto adidas tops, work in conjunction with Polar’s Wear Link™ technology to eliminate the need for a separate chest strap to monitor heart rate. Just snap the tiny Polar WearLink connector onto the front of the shirt and go. The data is sent to the Polar RS 800™ wrist-mounted running computer, which easily displays and records all information in real time. Simply put, your shirt talks to your running computer.

[…]The adiStar Fusion shoe has a strategically placed cavity in the midsole which can house the very light Polar s3™ Stride Sensor, making it easier to use, more comfortable and more consistently accurate than top-of-shoe systems. And you won’t even know it’s there when your shoe is talking to your running computer.

Information like speed and distance, chronograph functions, along with heart rate, are also shown on the RS800™ in real time. And when the workout is over, all data can be downloaded onto a computer so workouts can be easily managed and analyzed, meaning the whole system talks to you.”
