RFID electronic tag and manufacturing method and system thereof

Abstract

The embodiment of the invention provides an RFID electronic tag and a manufacturing method and system thereof. The RFID electronic tag comprises an RFID antenna and an IC chip. The first end of the IC chip is connected with the first end of the RFID antenna, and the second end of the IC chip is connected with the second end of the RFID antenna; the RFID antenna is used for receiving an external instruction, sending the external instruction to the IC chip, receiving information sent by the IC chip and sending out the information; the manufacturing material of the RFID antenna comprises conductive ink; the conductive ink comprises liquid metal, a polyvinyl alcohol solution and deionized water, or the conductive ink comprises liquid metal, a polyvinyl alcohol solution and dimethyl sulfoxide; the RFID electronic tag is applied to biological skin or artificial materials simulating the biological skin. According to the RFID electronic tag and the manufacturing method and system thereof provided by the embodiment of the invention, packaging is not needed, and the RFID electronic tag has relatively good tensile property and friction resistance.

Description

Technical field[0001]The present invention relates to the field of electronic tags, in particular to an RFID electronic tag and its fabrication methods and systems.Background technique[0002]RFIo Frequency Identification, RFID, is one of automatic identification technology, by wireless radio frequency mode, non-contact bidirectional data communication, read and write the recording medium (RFID electronic tag) by wireless radio frequency, thereby achieving identification target And data exchange purposes, it is considered to be one of the most developed information technology in the 21st century. RFID electronic tags are widely used in material management, production line automation, parking management and other item management and recording directions. The personnel management mainly passed the RFID tag card to realize personnel recognition. People who carry RFID tag cards often face the loss of label cards and embarrassing sites carrying inconvenience. Especially in the management o...

AI Technical Summary

Problems solved by technology

[0004] The shortcomings of the existing skin RFID electronic tags mainly include: 1. The flexibility of conductive ink

Labels prepared by patterning Ag or other non-flexible conductive substances on the skin are not stretchable enough

With human activities, the skin will be continuously stretched and compressed. This change can easily lead to the shedding of the non-flexible conductive material, or the breakage of the line, resulting in the failure of the label; 2. The friction resistance of the label is not enough

The combination of conventional conductive ink and skin is not good, and its own friction resistance is not good, which will cause the label to fail easily when it rubs against external objects; 3. In order to improve durability, some people will package the skin electronic label

However, after encapsulation, the skin will be closed, the air permeability of the skin will be seriously affected, and the encapsulation layer will cause discomfort to the human skin
