Fraunhofer IMS has developed a new RFID technology for the use in and on metal.

RFID (Radio-Frequency Identification) technology is established in numerous areas of application, from theft protection to monitoring of company sizes. Depending on the application, the frequency standards of low, high or ultra high frequency are used.

However, the application in metallic environments or on metallic surfaces is problematic. These can lead to standing waves or will impact the performance of the RFID transponder (tag). In addition, many use cases are subject to size restrictions in order not to endanger the usability of RFID-tagged tools, for example.

Fraunhofer IMS addresses these challenges with RFID technologies in the super-high frequency (SHF) range. The researchers are supported by the Fraunhofer FHR and other partners. The RFID-in/on-Metal technology improves the performance in metallic environments or on metallic surfaces and also enables the tags to be further reduced in size. In order to establish an SHF standard in the market, the Fraunhofer IMS also develop communication protocols for this frequency range.

Therefore the technology solution of Fraunhofer IMS contains a complete RFID system from reader to tag. It can be adapted to individual requirements and environments. The technology is already used for the management of tools and surgical instruments, i.e. their unique identification, tracking and life cycle management.
