Health and fitness tracking has undoubtedly taken off, with multiple wearable devices available on the market, such as wristbands and watches which monitor physiological parameters like heart rate. These are mostly intended to be used to gather data during fitness activities and do not guarantee high-quality measurements and data analysis meeting the quality standards imposed by the medical device industry. On the other hand, cardiologists can provide Holter devices for their patients to wear for an extended period of time in order to gather long-term heart activity data. These devices are hung from the neck and consist of a number of wires and sensors which all together make the equipment cumbersome and impractical. Umana T1 was designed to solve both these problems, finding a balance between quality of the data gathered as well as comfort and practicality.
