What do we call any type of smart device that is worn on or implanted in the body?

The term for any type of smart device that is worn on or implanted in the body is wearable technology. This category includes devices such as smartwatches, fitness trackers, and even medical implants like glucose monitors or pacemakers. Wearable technology is characterized by its ability to be integrated into daily life, providing users with real-time data and connectivity. These devices often feature sensors to monitor various health metrics, track activities, and enhance user interaction with information and communication technologies.

In contrast, geolocation refers to the identification of the real-world geographic location of an object, which is not specific to devices worn or implanted. Geofencing involves creating virtual boundaries in relation to a geographic location, often used in marketing or fleet tracking, but again does not relate to wearable devices directly. Jailbreaking pertains to overriding software restrictions on devices, typically smartphones, to allow the installation of unauthorized applications, which does not pertain to the classification of devices as wearable technology. Therefore, the definition of wearable technology precisely encompasses those devices designed for direct interaction with the wearer's body.
