The innovative SAW sensors are entirely passive in their function and are suited for object identification (RFID) and temperature measurement. The specific advantages are that they function dependably under extreme temperatures (-100°C to 400°C), and withstand shock or exposure to radiation. This makes them interesting for application in the automotive, heavy and chemical industries.

Because of their high gamma-ray resistance, the SAW sensors are suited for the medical or pharmaceutical industries, for example in the sterilisation process for contact-free identification of medical implants, stitching materials, operating devices, surgical instruments or blood storage. With respect to nuclear and energy policy, they could lead to an increase in safety standards, in that they enable consistent identification of radiation-activated components or processes.

In comparison to other technologies, the SAW sensors function with a piezoelectric crystal, which has a thermally higher destruction wave than integrated circuits and, as opposed to barcode technologies, is not sensitive to contamination. The SAW technology uses the 2.45GHz frequency range, and thus allows large reading distances of several meters.
