Inductive Positioning

Precise Detection

The inductive near-field detection technology developed by Fraunhofer IIS enables the precise detection of barrier breaches for a variety of applications, particularly in the fields of security, manufacturing, logistics and health care. Based on the geofencing concept, the system can be configured to demarcate and control a large physical area to efficiently protect people and objects.

How the IndLoc technology works

Developed at the Fraunhofer Institute for Integrated Circuits IIS, the IndLoc positioning technology is an economical solution for the three-dimensional real-time position determination of passive objects in a defined volume with high precision. To this end, a live conductor encloses a defined area of variable size and generates a weak alternating magnetic field within the perimeter.
The object to be positioned carries a small, passive coil, similar to an RFID transponder. This “positioning coil” generates a secondary magnetic field in the observed volume, which is registered by antennas and evaluated by the IndLoc system. Thus, a boundary breach – as well as the position, orientation and motion of the object to be located – can be recorded with high precision, without the object needing to contain active electronics.
Using suitable backend software, the captured positional data can be visualized, further processed or assigned specific patterns. In this way, predefined actions such as alarm notifications can be triggered for events such as boundary breaches.
