What type of IoT accessories are designed to be worn?

Wearables are a specific category of Internet of Things (IoT) accessories that are designed to be worn on the body to track health, fitness, and other personal data. This includes devices such as smartwatches, fitness trackers, and health monitors. Their primary purpose is to provide real-time information and facilitate seamless interaction with the user’s lifestyle and wellness activities.

Smart devices generally refer to a broader category of connected gadgets that can include various appliances and equipment around the home or office but are not specifically designed to be worn. Sensors can be integrated into wearables but also function independently in other types of devices, gathering data from the environment rather than the human body. Hubs serve as central points that connect multiple smart devices, allowing them to communicate, but they are not personal wearable devices. Therefore, the characteristics and intended use of wearables clearly distinguish them as the correct answer in this context.
