A method of preparing a RFID sensor tag comprising steps of: A). Printing conductive sensing ink/glue on substrate; B. Drying, curing and compressing the conductive sensing ink/glue to form a conductive antenna mixture with plural sensing materials; C). Bonding a chip on a RFID sensing antenna to form a RFID sensor tag; and D). Coating a protection layer on a top of the RFID sensor tag.
