Wearables are a fast-rising area in the Internet of Things. Consumers have shown a growing interest in smartwatch and wristband devices that can be used for things like contactless digital payments and fitness tracking. These connected devices tend to include biometric sensors enabling them to monitor things like heart rate and even blood oxygen levels, making them increasingly valuable tools not only in personal fitness, but in healthcare applications. What’s more, these biometric capabilities can even enable user authentication by identifying physiological patterns that are unique to the wearer.
While these are currently the most popular forms of wearable tech, a range of other form factors and applications are emerging: undershirts that can track the vital signs of race car drivers, compact heart rate sensors that can be slipped into a shirt pocket, smart glasses allowing police officers to scan the faces in a crowd, and even biometric rings that can detect signs of illness – these are just a few examples of the innovations that have been taking shape in wearable devices.
