Abstract
The invention relates to a sensor structure comprising at least one first layer containing an electrically conductive polymer, optionally mixed with a binder that constitutes a binding agent matrix, and at least one second layer, which is separate from and adjacent to the first layer or at a distance therefrom, or at least partly joined to the first layer, whereby the second layer comprises microcapsules containing either a basic or acidic substance, optionally mixed with the binder, the acidic or basic substance changing the electrical conductivity of the polymer when released from the microcapsules. The invention also relates to the manufacturing method and the use of the sensor structure.
Claims40
A sensor structure, characterized in comprising
- at least one first layer having an electrically conductive polymer optionally mixed with a binder that forms a binding agent matrix, and
- at least one second layer, which is apart from and next to the first layer or at a distance therefrom, or at least partly joined with the first layer,
- whereby the second layer comprises microcapsules that either contain an acidic or a basic substance, optionally mixed with the binder, the acidic or basic substance changing the electrical conductivity of the polymer when releasing from the microcapsules.
A method for manufacturing a sensor structure, characterized in the manufacturing of, according to the method,
- at least one layer containing an electrically conductive polymer, which is optionally mixed with a binder, and
- at least one second layer, which is adapted to be separate from and adjacent to the first layer or at a distance therefrom or at least partly connected to the first layer,
- whereby the second layer is formed from microcapsules, optionally mixed with the binder, the microcapsules containing a base or an acid.
A method for manufacturing a product containing a sensor structure, characterized in that
- an electrically conductive polymer (3) is added to the product, optionally mixed with a binder;
- and
- microcapsules (2) containing basic or acidic substances are added to the product, optionally mixed with the binder.
