BeatInfo provides the user with physiological signals for cardiopulmonary fitness and fatigue recovery as well as real-time suggestions on improving athletic performance and avoiding injuries during exercise. By placing the device on the chest, BeatInfo continuously monitors cardiac status, as well as respiration, air pressure and body motion. The device is designed to not obstruct the user during exercise. It is mall yet functional, while the internal rechargeable battery lasts an entire day. BeatInfo uses biocompatible and highly elastic, breathable fabric fibers to ensure comfortability for long wearing times.
