The technology that underlies the functionality of smart wearables is primarily composed of sensors and software that track user data. These devices, such as smartwatches and fitness trackers, utilize various sensors to monitor heart rates, sleep patterns, and activity levels. Their embedded software processes this data and provides users with actionable insights to improve their health and wellness. Additionally, connectivity features allow wearables to synchronize with smartphones, enabling further data analysis and enhancing user engagement through notifications and personalized recommendations.
