About Battery-Free RFID Wireless Sensors
Low-frequency technology is ideal for reading through liquids or solid materials – including composites such as carbon fiber.

Examples of Low Frequency (LF) Passive RFID Wireless Sensors
Embedded Carbon Fiber Sensor (Temperature, Vacuum, Pressure)
LF RFID sensors can be so small that they can fit in the honeycomb cells of a composite structure. Since they are battery-free, they can operate for decades. The low-frequency magnetic waves travel right through the carbon fiber so the embedded sensor can be read. Watch our Demo Video & Learn More.
Rugged Battery-Free Tire Pressure and Temperature Monitoring System (TPMS)
Phase IV designed the LF RFID sensor ASIC with Crane Aerospace for use in the extremely harsh environment of aircraft wheels. See more information on the Aerospace Solutions & Demos page.
Featured in RFID Journal.
Wireless Temperature Monitoring in Food Processing
Ideal for monitoring the internal temperature of small objects. The small mass of the sensor has minimal effect on the heating of the object being monitored.
As featured in Food Engineering journal, “The Fantastic Voyage of a Temperature Probe” , featuring a partnership between Phase IV and Campbell’s Soup.
