A so called ‘world’s first’ production-ready Bluetooth low energy heart-rate chest belt has been announced by Nordic Semiconductor ASA in conjunction with Dayton Industrial Co. Ltd.

This product enables anyone with a smartphone that has the latest version 4.0 of Bluetooth to be able to set-up and use a wireless heart-rate (HR) belt within seconds and so spur the development of a whole new range of Bluetooth low energy-based health and fitness apps. This could ­include new ways of collecting, interpreting, and displaying HR training data – including motivational social media-based data and progress sharing. The nRF8001’s ULP performance and size enables the Bluetooth low energy heart-rate belt to run for up to 1.5 years from a CR2032 coin cell under typical usage conditions (1-hour per day). It is 1.1cm thick and is compact at 3.8 x 6.5 cm.
