PAGE TITLE
Overview
PAGE SUMMARY
This technology is for a sensor product that measures the moisture content of a material using RFID tags and readers. The system comprises a plurality of RFID tags embedded in the material, each having a unique identifier and electromagnetic properties that vary with the moisture content of the material. The system also comprises a plurality of RFID readers that transmit radio signals to the RFID tags and receive backscattered signals from the RFID tags. Finally, a processor determines the moisture content of the material based on the electromagnetic properties of each RFID tag and its corresponding identifier.
ADVANTAGES
TITLE:Key Advantages
Scalability and flexibility
Non-invasive and non-destructive measurement of moisture content
High accuracy and sensitivity
Low cost and maintenance
Wireless and remote operation
Problem Solved
TITLE:Problems Solved
Invasive and destructive sampling of material
Low accuracy and sensitivity due to environmental interference
High cost and maintenance due to complex hardware and calibration
Wired and local operation that limits mobility and coverage
Fixed and rigid configuration that limits adaptability and customization
Timely and automatic wireless notification of status changes to deliver higher standard of care or enable better performance in various applications
APPLICATIONS
TITLE: Market Applications
