Abstract

A method and apparatus, the method comprising: transferring a layer of two dimensional material from a liquid surface onto a layer of woven electronic fabric; wherein the woven electronic fabric comprises a plurality of conductive strands and a plurality of non conductive strands such that the layer of two dimensional material and woven electronic fabric form a sensor.

First claim

We claim:

1. A method comprising:
providing a layer of woven electronic fabric, the woven electronic fabric comprising a plurality of conductive strands and a plurality of non conductive strands such that a plurality of air gaps are formed between adjacent strands;
providing a layer of two dimensional material on a liquid surface;
overlaying the layer of two dimensional material with the layer of woven electronic fabric; and
using the plurality of air gaps to transfer the layer of two dimensional material from the liquid surface onto the layer of the woven electronic fabric;
wherein the layer of two dimensional material and the woven electronic fabric form a sensor; and
wherein the two dimensional material comprises graphene.

2. A method as claimed in claim 1 wherein the graphene is functionalized with at least one of: colloidal quantum dots, metallic nanoparticles, or bio-functional molecules.

3. A method as claimed in claim 1 wherein the two dimensional material is transferred to the woven electronic fabric by a capillary action.

4. A method as claimed in claim 1 wherein the transferred two dimensional material is suspended between strands of the woven electronic fabric.

5. A method as claimed in claim 1 further comprising providing a filler material between strands of the woven electronic fabric.

6. A method as claimed in claim 5 wherein the filler material is configured to be transparent to a parameter that is to be sensed by the two dimensional material.

7. A method as claimed in claim 5 wherein the filler material comprises a dielectric.

8. A method as claimed in claim 1 further comprising providing a further layer of woven electronic fabric overlaying the two dimensional material.

9. A method as claimed in claim 1 wherein the layers of the woven electronic fabric are magnetized.

10. A method as claimed in claim 1 further comprising providing at least one layer of woven electronic fabric on a backing substrate.

11. A method as claimed in claim 10 further comprising providing read out electronics on the backing substrate.

12. A method as claimed in claim 1 wherein the woven electronic fabric comprises at least one of: parallel conductive strands, or perpendicular conductive strands.

13. A method as claimed in claim 1 further comprising providing a protective polymer layer overlaying the layer of two dimensional material.
