Abstract

An electrically anisotropic pressure sensitive assembly comprises 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. 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 changes in accordance with the pressure exerted thereon. 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.
