== History ==
In 1975, there was no accurate way to record heart rates during training, and the idea of a wireless, portable heart rate monitor was conceived on a cross country skiing track in Finland. Polar was founded in 1977, and filed its first patent for wireless heart rate measurement three years later. In 1982, Polar launched the first ever wearable wire-free heart rate monitor.
