Strapless Heart Rate Monitor

Found in a magazine listed as 'innovation': The first heart rate monitor that does not require you to wear a band around your chest.
So if you are a runner and want to train with a HRM but hate the band around your chest? Here is the solution. The Mio Alpha.

Using an optical sensor it measures your blood flow in your wrist to determine your heart rate.

They used Kickstarter to raise capital so you can find more info including some video's on the site. what I learn is that it is a simple monitor, using a led to indicate if your in your training zone. But for things like GPS, speed, distance and the like they advise the use of you favourite App on your Smartphone.

The watch is available from amzon.com.
