Wearable technologies are multimedia-capable computerized devices that can be worn on or around the body as accessories with digitalized functionalities and wireless connectivity. Examples of wearable technologies include smartwatches, bracelets, and rings; intelligent fabrics and glasses; virtual reality (VR) headsets; smart medical devices; and brain-monitoring technology. This entry introduces the concept of wearable technologies; discusses their features, uses, and applications; and examines future development.

Wearable Technologies Defined

Wearable technologies incorporate high-tech miniaturized components (e.g., sensors, microcontrollers and wireless connectors, touch screens, microphones, amplifiers, temperature and water resistance trackers). Sensors are particularly important because they continuously collect physical, electrical, and chemical properties of the body and the local environment and then, through microcontrollers and algorithms, feed back that information to various interlocutors.

Because of these sensors, wearable technologies are ...
