Abstract

A detector system is provided suited for detection of environmental effects. The sensing element is constructed in the form of a grid and is designed in particular for the detection of moisture. Said structure is suited for simple deployment, optionally embedding into concrete, and detection of environmental effects on a large scale such as tunnels, bridges, dams and quays.

Claims

1. A detection system, wherein it comprises two or more tracks arranged with a substantially fixed mutual distance in a structure of a substantially insulating material, wherein the tracks are longitudinal detection tracks in one direction, optionally two directions wherein tracks are substantially 90°

to each other, wherein each track detects an environmental effect in proximity of the track.

2. System according to claim 1, wherein tracks are printed as electrical conductors on an insulating substrate.

3. System according to claim 2, wherein the substrate is flexible.

4. System according to claim 2, wherein the substrate is a diffusion barrier.

5. System according to claim 1, wherein the structure is open in that the tracks are arranged as wires in a fishing net like structure, wherein each wire comprises a first electrical conductor and a second electrical conductor, within said two electrical conductors are separated from each other by an electrical insulator.

6. System according to claim 2, wherein the insulating is arranged with a functional material in the core located substantially between the electrical collectors so that the environmental effects on the functional material will change the electrical properties readable from the electrical conductors.

7. System according to claim 1, wherein a functional material is arranged between at least two conductors belonging to two tracks where said tracks intersects each other in such a way that the environmental on the functional material change electrical properties readable by the electrical conductors.

8. System according to claim 1, wherein the structure is at least a module provided with end contacts along the periphery for connection to further modules.

9. System according to claim 1, wherein the structure is arranged for operating in a plurality of modes comprising AC current mode, DC current mode, a third mode for applying a voltage of a first conductor on a first wire and on a first wire on a second wire, and a fourth mode by applying a voltage on a second conductor on the first wire and on the second conductor on the second wire;

for measuring values such as impedance and resistance, as well as for current supply.

10. System according to claim 3, wherein the substrate is a diffusion barrier.

11. System according to claim 3, wherein the insulating is arranged with a functional material in the core located substantially between the electrical collectors so that the environmental effects on the functional material will change the electrical properties readable from the electrical conductors.

12. System according to claim 4, wherein the insulating is arranged with a functional material in the core located substantially between the electrical collectors so that the environmental effects on the functional material will change the electrical properties readable from the electrical conductors.

13. System according to claim 5, wherein the insulating is arranged with a functional material in the core located substantially between the electrical collectors so that the environmental effects on the functional material will change the electrical properties readable from the electrical conductors.

14. System according to claim 2, wherein a functional material is arranged between at least two conductors belonging to two tracks where said tracks intersects each other in such a way that the environmental on the functional material change electrical properties readable by the electrical conductors.

15. System according to claim 3, wherein a functional material is arranged between at least two conductors belonging to two tracks where said tracks intersects each other in such a way that the environmental on the functional material change electrical properties readable by the electrical conductors.

16. System according to claim 4, wherein a functional material is arranged between at least two conductors belonging to two tracks where said tracks intersects each other in such a way that the environmental on the functional material change electrical properties readable by the electrical conductors.

17. System according to claim 5, wherein a functional material is arranged between at least two conductors belonging to two tracks where said tracks intersects each other in such a way that the environmental on the functional material change electrical properties readable by the electrical conductors.

18. System according to claim 6, wherein a functional material is arranged between at least two conductors belonging to two tracks where said tracks intersects each other in such a way that the environmental on the functional material change electrical properties readable by the electrical conductors.

19. System according to claim 2, wherein the structure is at least a module provided with end contacts along the periphery for connection to further modules.

20. System according to claim 3, wherein the structure is at least a module provided with end contacts along the periphery for connection to further modules.
