  4. 3. Antenna-based passive UHF RFID sensor tags : Design and application

    Författare :Jinlan Gao; Hans-Erik Nilsson; Johan Sidén; Emmanouil Tentzeris; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : RFID, as a low cost technology with a long life time, provides great potential for transmitting sensor data in combination with the ordinary ID number. The sensor can, for example, be integrated either in the chip or in the antenna of an RFID tag. LÄS MER

  5. 4. Flexible Circuits and Materials for Creating Large-Area RFID Reader Antenna Systems

    Författare :Xiaotian Li; Johan Sidén; Henrik Andersson; Jonny Johansson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One of the applications for RFID technology is to monitor and position RFID-tagged objects over large volumes. To achieve this, one possible option is to implement RFID reader antennas, which are relatively thin but with significantly large areas, and place them beneath the RFID-tagged objects. LÄS MER

  7. 5. Development of Wireless Biosensors Integrated into the Radio Frequency Antenna for Chipless and Battery-less Monitoring of Biological Reactions

    Författare :Atefeh Shafaat; Tautgirdas Ruzgas; Sebastian Björklund; Javier Sotres; Jessica Neilands; Daniel Aili; Malmö universitet; []
