  • Passive RFID temperature sensors with liquid crystal elastomers
    Patent number: 10909438
    Abstract: Passive radio frequency identification (RFID) real-time temperature sensors based on programmable liquid crystal elastomers (LCEs) are provided. The sensors can be used for monitoring the temperature for various items, including perishable goods, foods, and medicines in the cold supply chain. The sensors can convey changes in temperature through a controlled shift of the operating frequency in the RFID ultra high frequency (UHF) band.
    Type: Grant
    Filed: July 9, 2020
    Date of Patent: February 2, 2021
    Assignee: The Florida International University Board of Trustees
    Inventors: Stavros Georgakopoulos, Yousuf Shafiq
