RFID Sensors on the Rise

RFID is moving beyond wireless identification alone to wireless sensing of parameters such as temperature, humidity and much more. RFID is booming and now accounts for the largest number of silicon integrated circuits made of any one particular type. In addition to more than 20% growth over the next few years, there is much more to come. Communication protocols, such as NFC or UHF Gen 2, are now being employed to transfer sensor data in addition to identification data. In some cases the RFID IC has a sensor built in, in other
