Wearable Device
Definition
A subcategory of IoT device worn on the body, typically a fitness tracker, smartwatch, or medical monitor. Wearables generate high-frequency sensor data including step counts, heart-rate readings, blood-oxygen levels, GPS tracks, and sleep stages, all timestamped and usually synchronised to a cloud account.

Common questions
Where is wearable device evidence usually recovered from?+
Both the device itself and the paired smartphone app or cloud account can hold relevant data, and the cloud copy often retains a longer history than the device's limited on-board storage, so both sources are typically pursued.
How reliable is wearable sensor data as forensic evidence?+
Consumer sensors are optimised for wellness trends, not evidentiary precision, so heart-rate or GPS readings can drift or misfire. Investigators corroborate wearable data with other timeline evidence rather than relying on it alone.
