Wearable technology refers to electronic devices that can be worn on the body, often incorporating sensors to collect data and provide real-time feedback. Common examples include smartwatches, fitness trackers, and health-monitoring devices. These wearables can track physical activity, monitor vital signs, and even detect health anomalies. The data collected can be synced with smartphones or cloud services for analysis and personalized insights. Advancements in wearable technology are leading to more compact, comfortable, and feature-rich devices, making them increasingly popular for health and fitness applications.
