Abstract

The present invention relates to an aerosol-generating article, adapted to be electrically heated by an aerosol-generating device. The aerosol-generating article comprises an aerosol-generating substrate, an optical information storage element storing information in a grid pattern with a plurality of segments comprising at least one alterable segment. The at least one alterable segment comprises a first layer and a second layer, wherein at least one optical property of at least one layer is adapted to be altered. The invention further relates to a method for manufacturing an information storage element, an aerosol-generating system comprising an aerosol-generating article and an aerosol-generating device and the use of a multi-layered information storage element on an aerosol-generating article to provide alterable supplemental information about the aerosol-generating article.

First claim

1 - 15 . (canceled)

16 . Aerosol-generating article, adapted to be electrically heated by an aerosol-generating device, the aerosol-generating article comprising
an aerosol-generating substrate, an optical information storage element storing information in a grid pattern with a plurality of segments comprising at least one alterable segment, wherein the at least one alterable segment comprises a first layer and a second layer,
wherein at least one optical property of at least one layer is adapted to be altered,
wherein the second layer is at least partly deposited on the first layer and is formed in a grid pattern with a plurality of rectangular segments comprising at least one alterable segment.

17 . Aerosol-generating article, according to claim 16 , wherein the optical information storage element is adapted to be altered from a first state to a second state, wherein at least one optical property of the at least one alterable segment differs in between the first state and the second state.

18 . Aerosol-generating article, according to claim 17 , wherein in the first state the segments form a first optically readable code and wherein in the second state the segments form a second optically readable code, wherein the first optically readable code and the second optically readable code each encode different information content.

19 . Aerosol-generating article, according to claim 17 , wherein at least one optical property of the at least one alterable segment uniformly differs in between the first state and the second state.

20 . Aerosol-generating article, according to claim 16 , wherein the first layer comprises at least one material different to one or more materials of the second layer.

21 . Aerosol-generating article, according to claim 16 , wherein two or more different materials are disposed in the first layer and/or the second layer.

22 . Aerosol-generating article, according to claim 16 , wherein a material of the second layer overlays a different material of the first layer.

23 . A method for manufacturing an information storage element, in particular for an aerosol-generating article, the method comprising the steps of:
depositing a first material layer on a surface, depositing a second material layer at least partly on the first material layer, wherein the first material layer is formed in a first pattern, and
the second material layer is formed in a second pattern,
wherein the second pattern at least partially corresponds to the first pattern and is formed in a grid pattern with a plurality of rectangular segments comprising at least one alterable segment.

24 . Method according to claim 23 , wherein the second layer is formed in a second pattern while depositing the second layer.

25 . Method according to claim 23 , wherein the forming comprises to induce a physical or chemical material change.

26 . Method according to claim 23 , wherein the forming comprises irradiation with an electromagnetic radiation.

27 . Method according to claim 23 , wherein the method further comprises the step of making material processable by inducing a physical or chemical material change before or during depositing the first material layer or second material layer.

28 . Aerosol-generating system comprising an aerosol-generating article and an aerosol-generating device,
the aerosol-generating article being adapted to be heated in the aerosol-generating device, wherein the aerosol-generating article comprises an information storage element with at least two layers, wherein the second layer is at least partly deposited on the first layer and is formed in a grid pattern with a plurality of rectangular segments comprising at least one alterable segment, wherein the information storage element is alterable from a first state to a second state by altering at least one layer of the information storage element, wherein the aerosol-generating device is adapted to read the information storage element in the first state and in the second state.

29 . Aerosol-generating system according to claim 28 , wherein the aerosol-generating device is adapted to read out more than 1 bit of information both in the first state and in the second state.

30 . Use of a multi-layered information storage element on an aerosol-generating article to provide alterable supplemental information about the aerosol-generating article, wherein a second layer is at least partly deposited on a first layer and is formed in a grid pattern with a plurality of rectangular segments comprising at least one alterable segment, wherein at least one layer comprises a plurality of segments comprising at least one alterable segment.
