Electrically conductive assembly

A sensor comprising a first pair of conductors situated to a first side of a carbon composite structure and a second pair of conductors situated to a second side of the carbon composite structure, wherein the second set of conductors are electrically anisotropic pressure sensitive assemblies, each of the electrically anisotropic pressure sensitive assemblies comprising a contained quantity of electrically conductive particles including first electrically conductive particles, which first electrically conductive particles are magnetite particles, wherein the quantity of magnetite particles includes a distribution of particle sizes between sub-micron and tens of microns, and wherein the magnetite particles have a plurality of planar faces, adjacent planar faces connected at a vertex, the particles each having a plurality of vertices wherein the magnetite particles are irregular in shape, the resistance and/or capacitance of the electrically conductive assembly changing in accordance with the pressure exerted thereon, and wherein the assembly includes at least two electrically conductive elements, the quantity of electrically conductive particles being contained in interstices between the at least two electrically conductive elements.
