The ePulse works by integrating light sensor and microchip technology–the same type used in hospital heart rate monitors–to accurately read the pulse from the forearm. Once on your arm, the ePulse continuously acquires and shows your current exercise heart rate while calculating calories burned based on your heart rate and personal profile. If you use the ePulse several times a day, it automatically compiles your calories burned into a grand daily total, including when your activities consist of moving around the office or doing work around the house.
