RFID Tag-Reader System for Long Range Remote Sensing and Identification


Executive Summary


RFID tags are employed in a multitude of applications and industries, such as transportation, animal identification, retail and many others. However, these applications are typically limited to instances where there is free access to the location of the RFID chip. This MSU developed technology allows a RFID tag to be implemented in a location that will be permanent and traditionally inaccessible while providing a reader to access the RFID tag’s identification and sensing information.  Modified transmission allows versatility in application.


Description of Technology


Passive RFID tags operate by receiving a penetrating radio wave from a reader and uses that input to power transmission of a response and can be used to power a sensing element. The conventional RFID tag transmits information – typically with an IP address – at the same radio frequency as the input. However, environmental issues between the RFID reader and tag will reflect penetrating radio waves from the reader and cause interference. The new MSU technology allows a RFID tag to transmit information at a radio frequency or frequencies different from the penetrating frequency.  Input energy can be utilized


Key Benefits

  • Reduces interference in underground/packaging applications
  • Multiple sensors utilize one RFID tag
  • Passive energy harvesting prolongs lifetime



  • Package tracking
  • Underground monitoring
  • Passive sensing
  • Multi-sensor data transmission
