The technology that enables the creation of smart wearable devices typically involves sensor technology, connectivity protocols, and an embedded operating system. These devices, such as smartwatches and fitness trackers, use sensors to gather data on physical activity, health metrics, or environmental conditions. They rely on Bluetooth or Wi-Fi for connectivity, allowing data synchronization with smartphones or cloud services. Additionally, smart wearables utilize software applications to process and analyze collected data, providing users with actionable insights into their performance and well-being.
