Embodiment 1

[0028] like figure 1 As shown, a waterproof invisible barcode based on an electrical detection method includes a substrate 1, a barcode electrode 2 and a connecting electrode 3, the barcode electrode 2 and the connecting electrode 3 are located on the substrate, and the barcode electrode 2 is located on the connecting electrode 3, and several barcode electrodes 2 are connected together by connecting electrodes 3, and both the barcode electrodes 2 and the connecting electrodes 3 are transparent.

[0029] In the present embodiment, the base 1 is transparent plastic polyethylene terephthalate (PET), which has a certain degree of flexibility, so that devices made of polyethylene terephthalate also have a certain degree of flexibility. The flexibility can be attached to some non-planar surfaces. Further, the area of ​​the substrate 1 is 8cm*5cm. Described barcode electrode 2 has six electrodes, and its width is respectively 0.4cm, 0.4cm, 0.4cm, 0.8cm, 0.8cm, 0.8cm, and the length...

Embodiment 2

[0032] In this example, on the basis of Example 1, the electrical output of the barcode prepared in Example 1 is tested to verify the feasibility of the invisible barcode proposed by the present invention. In this example, we use human skin as the test material. Furthermore, we swipe each barcode electrode at a constant speed with our finger, and then observe whether its output electrical signal is sequentially related to the width of the barcode electrode.

[0033] Here's how it works: Initially, both the finger and the barcode electrodes are electrically neutral. When the finger touches the ITO on the barcode and rubs against it, equal and opposite dissimilar charges will be generated in the finger and the ITO, and when the finger leaves the ITO on the barcode, the charge will flow out of the barcode electrode, In this way, a corresponding pulse electrical signal output will be generated at the bar code electrode. When the fingers pass across all the barcode electrodes at a ...

Abstract

The invention discloses a waterproof invisible barcode based on an electrical detection method and a detection method, comprising a substrate, a plurality of barcode electrodes and a connection electrode, the barcode electrodes and the connection electrodes are located on the base, and the barcode electrodes are all located on the same side of the connection electrode. On the side, several bar code electrodes are connected with the connection electrodes, and the bar code electrodes and the connection electrodes are both transparent; the electrical detection method of the present invention is based on the principle of triboelectricity, which enables the bar code to be made of transparent materials. The barcode pattern produced in this way is invisible; different barcode electrode widths correspond to different widths and amplitudes of the output electrical signal, so the barcode can be identified by the width and amplitude of the output pulse electrical signal.

Description

technical field [0001] The invention relates to the technical field of barcodes, in particular to a waterproof invisible barcode used in the fields of product anti-counterfeiting and information security, as well as its detection principle and detection method. Background technique [0002] Barcode is a common anti-counterfeiting mark in life. It forms a graphic identifier through different widths and blanks of barcodes and different reflectivity according to certain coding rules. It can carry a lot of information, such as production location, production date, Mail starting and ending points, product information and book classification, etc. Therefore, it has a wide range of application scenarios, especially in security information, product identification. In recent years, it has also been widely used in the logistics industry. Encoding various information through barcodes can save a lot of manpower and time. In addition, the current barcodes are based on the principle of...
