Wearables are electronic devices designed to be worn on the body, often integrating sensors, connectivity, and computing capabilities. Common examples include smartwatches, fitness trackers, augmented reality glasses, and health-monitoring devices. They are used for tracking physical activity, monitoring vital signs, enabling communication, and providing real-time data. The wearables market has grown rapidly due to advances in miniaturized technology, health awareness, and integration with smartphones and cloud services.
