Embodiment Construction

[0042] Electron sintering is employed to modify the impedance or surface impedance of a deposited (printed, dispensed, spin-coated, etc.) layer of material, for example a dry layer based on a nanoparticle printing ink. Impedance is usually a complex variable with both real and imaginary parts. Either or both of the impedance components (real or imaginary) can be used for reading. However, if the contacts on the reader face are capacitive, more reliable readings can be obtained using the real part of the impedance. In the following, electronic coding denotes this controlled impedance structure.

[0043] The electronic encoding may be in the form of a barcode consisting of lines of varying resistivity. The barcodes are produced wholly or partly with ink, the resistivity of which can be adjusted later by electronic sintering techniques. An example of such an ink is the silver nanoparticle ink from Advanced Nano Products. Lines of coded adjustable resistivity can be produced i...

Abstract

The present publication discloses an electronic code, comprising a substrate (105, 10) of essentially electrically non-conducting material,several electrically conducting code elements (108) formed on the substrate. In accordance with the invention at least one code element (101, 108) comprises an editable area (109), the conductance of which can be altered electrically.

Description

technical field [0001] The invention relates to a programmable printed electronic code according to the preamble of claim 1 . [0002] The invention also relates to a manufacturing method for the printed code, and a programming device. Background technique [0003] According to the prior art, optically readable barcodes as well as remotely readable RFID identifiers are used in the transportation of goods. [0004] Barcodes have the advantage of being a standardized technology, but this technology requires visible markings and reading technology at least at a visual distance, thus limiting the range of applications. Visible markers make the technology vulnerable to abuse. [0005] RFID technology has many advantages over the bar code technology described above, including long-range readability and the ability to completely hide the bar code in the product, which can be used to prevent counterfeit codes. However, the identifiers used in this technology are significantly mor...
