Heart rate monitor without a chest strap
The Beurer PM 100 finger sensor uses a glove to check your heart.
It takes German engineering to figure out how to make a heart rate monitor without one of those chest belts that can get pretty irritating during a workout.
From German company Beurer GmbH, this heart rate monitor is based on a technique called Plethysmography. It uses a sensor to measure light that is reflected by the bloodstream from an artery in your finger. Not only can this be used to measure your pulse but it can also be used to keep track of your blood pressure.
The LCD screen provides constant feedback that makes it ideal for athletes on the go and the ergonomic design of the glove acts like a second skin and is definitely more comfortable to wear than a bulky watch with a chest strap.
