1. An electrically conductive paper structure comprising a paper structure having electrodes formed from an electrically conducting ink, wherein the ink is substantially absorbed into the paper structure so that there is no substantial increase in the thickness of the paper structure, wherein the increase in the thickness of the paper structure due to the presence of the ink is less than 50 μm, a substantial part of the ink being located within the paper structure is greater than 50% of the ink, and the electrodes are embedded within the paper structure to a depth of 10 μm to 80 μm.
