What is Wearable Technology?

Quick answer

Electronic devices worn on the body, such as smartwatches and fitness trackers, that collect data and provide connected features.

Wearable Technology, explained

Wearables include smartwatches, fitness bands, smart rings, wireless earbuds, smart glasses, and specialized medical devices like continuous glucose monitors. They use sensors such as accelerometers, heart-rate monitors, GPS, and temperature sensors to track activity, sleep, and health indicators, and they sync with smartphones for notifications and analysis.

In healthcare, some wearables have regulatory clearance for specific functions, such as detecting irregular heart rhythms, and support remote patient monitoring. Consumers use them for motivation, safety features like fall detection, and contactless payments. Limitations include varying accuracy across devices and skin tones, battery life, and the sensitivity of the health data collected. Users should review privacy settings and understand how their data is stored and shared.
