X-Change Tests SAW-Based RFID Tags at Extreme Temperatures

DALLAS /BUSINESS WIRE/ -- X-Change Corporation's wholly owned subsidiary, AirGATE Technologies Inc. has successfully tested its surface acoustic wave (SAW) tags to 700°F (371°C).

Working with an undisclosed client, AirGATE SAW tags were heated to a temperature of 700°F and then read with AirGATE's SAW reader.

"SAW tags work well in extreme temperatures, and we were pleased to demonstrate this capability," stated Mike Sheriff, president and chief executive of X-Change Corp. "Many RFID applications are in harsh environments that are well-suited to SAW technology and represent potential opportunities for our company," added Sheriff. X-Change is positioned to ship SAW RFID systems in volume. This, he said, is the result of an exclusive national agreement for sale and support of SAW RFID systems signed in January with Carinthian Tech Research, a leading Austria-based developer of SAW RFID devices and technology.

The basic SAW device is a thin metal film structure deposited on top of a piezoelectric crystal substrate with no power supplies. It reflects radio signals based on the pattern etched onto its surface. These reflections can be decoded into data. In addition to RFID, SAW devices make very accurate temperature sensors and also work well in the presence of liquid and metals.
