Moisture sensing using radio frequency identification (RFID)

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

 

Healthcare: to detect moisture levels in diapers and incontinence products for infants and elders, the level of fluids in an IV-bag, in bandages related to wound healing, infection, dehydration, etc.
