Embodiment Construction

[0015] Such as figure 1 As shown, the new piezoelectric ceramic label has a piezoelectric ceramic sheet 2, and is composed of a conductive layer 1 coated on two planes of the piezoelectric ceramic sheet 2, and the conductive layer 1 on the two planes is not conductive.

[0016] Such as figure 2 The identification system for the above-mentioned new piezoelectric ceramic label is shown, which includes a new piezoelectric ceramic label to be labeled, an impedance analyzer and a computer, and the conductive layers on both sides of the new piezoelectric ceramic label pass through the wire and the impedance analyzer. connection, the impedance analyzer is connected to the computer.

[0017] Such as figure 2 As shown, the PZT label is pasted on the structure to be tested by gluing or other methods, and the computer controls the impedance analyzer to give the label a sweep frequency driving signal. At the same time, the impedance analyzer receives the PZT response signal and transm...

Abstract

The invention aims to provide a piezoelectric ceramic novel label, and an identification system and an identification method for the piezoelectric ceramic novel label for meeting a protection requirement on special goods. The piezoelectric ceramic novel label has a piezoelectric ceramic sheet, wherein conducting layers are coated on two planes of the piezoelectric ceramic sheet; and the conducting layers on the two planes are not conducted. The identification system comprises the piezoelectric ceramic novel label to be labeled, an impedance analyzer and a computer, wherein the conducting layers on the two planes of the piezoelectric ceramic novel label are connected with the impedance analyzer by leads; and the impedance analyzer is connected to the computer. The impedance characteristic information of the piezoelectric ceramic (lead zirconate titanate (PZT)) label is correlated with PZT materials, glue water, structural physical characteristics and the like, so the PZT label is strong in uniqueness and relatively simple to identify and can be used as a special label.

Description

technical field [0001] The present invention belongs to the field of technology requiring high performance special labels. Background technique [0002] Labels are tools used to mark and identify items. At present, there are many kinds of labels on the market, which can be divided into physical labels, electronic labels and special labels according to the form of existence. The physical label is a brief label used to indicate the product name, weight and other information of the item, such as package labels, commodity packaging barcode labels, and so on. Physical tags are easy to use and low in cost, but are easily damaged and changed. The spatial coupling of the radio frequency signal is realized through the coupling element between the electronic tag and the reader, and in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. Electronic tags can identify high-speed moving objects and can identify multiple tags at ...
