Polar Electro is a pioneer in wireless heart rate monitoring technology, founded in Finland in 1977. Since its inception, the company has been at the forefront of sports physiology and fitness technology, catering to professional athletes and fitness enthusiasts globally.

While the brand maintains its headquarters, research, and design operations in Kempele, Finland, the actual manufacturing of its consumer electronics and sensors is primarily outsourced to manufacturing hubs in China and other Asian territories to meet global demand. Despite being a major player in the wearable technology market, Polar Electro remains a privately held company, preserving its Finnish identity and specialized focus on cardiovascular tracking electronics.
