Organic transistor RFID

Anyone has any information about the design of an RFID tag usng organic transistors. Alot is written in the literature about the potential of OFET for RFID circuits but no real circuit has been designed. Anything concerning analog circuit design based on OFET will also help.
Thanks i advance

Refer to the book named analog circuit design using organic field effect transistors by Nicholas ***.
Should be helpful I guess

Here is a link where to buy it. It should be #5 in the list.
