The technology that helps to connect wearable devices to the internet is known as IoT (Internet of Things). Through this technology, wearables like fitness trackers, smartwatches, and health monitors transmit data to connected systems via the internet. This enables real-time monitoring of vital signs or physical activity, allowing users to track their health and performance metrics effectively. IoT also facilitates a seamless integration of wearables into broader health systems, enhancing healthcare delivery and data analytics. As IoT advances, it significantly enriches the functionality of wearable devices.
