1. A printed RFID sensor tag comprising:
- a substrate, a RFID sensor arranged on a top of the substrate, and a protective layer covering the RFID sensor;
the RFID sensor including a RFID sensing antenna and a chip adhered on the RFID sensing antenna, wherein the RFID sensing antenna is partially or totally made of conductive sensing ink/glue printed on the top of the substrate, and the conductive sensing ink/glue consists of conductive ink/glue and multiple sensing materials;
wherein the RFID sensing antenna includes a first part, a second part, and a sensing part, wherein a first distal segment of the first part separates from a second distal segment of the second part so as to produce an open circuit between the first distal segment of the first part and the second distal segment of the second part, wherein a chip adheres on a connection portion of the first part and the second part, the sensing part is coupled with the first segment of the first part and the second segment of the second part;
the first part and the second part are made of conductive ink/glue, and the sensing part are made of conductive sensing ink/glue, wherein the sensing part is a normal open circuit and changes to a closed circuit after being influenced by multiple sensed targets.
