Passive Wireless Sensing Powered by Chameleon Self-Tuning Technology (Internet of Things & WSN USA 2013)

• RFMicron has developed a new circuit embedded into a standards-compliant RFID chip that allows the chip to re-tune itself to adjust for environmental changes that would normally disrupt RF communications.

• That characteristic - adjusting to the environment - can be logically reversed and used for sensing.

• Devices using the chip can be designed so that a variety of different properties can be sensed.

• To demonstrate the principle, a simple moisture sensor has been successfully prototyped

RFMicron produces integrated circuits for mission-critical RFID tags and passive wireless sensors. The company's patented Chameleon™ technology enables a new level of systems performance reliability for conventional RFID applications. In addition, RFMicron chips facilitate inexpensive, no-battery, maintenance-free wireless sensors that have not been possible with other wireless technologies.
