The new sensor combines inductive and capacitive proximity sensing principles. The sensor detects the presence of an occupant exploiting the shielding effect of the electric field while its inductive ...

Instead, the monitor works via a small sensor placed just below the surface of your skin. You need to place the accompanying screen monitor above the system to get your glucose reading.

Abstract: Context-centric sensor-based proximity detection (or, contextual co-presence detection) is a promising approach to defend against relay attacks in many mobile authentication systems, ...
