Abstract
An electrically responsive composite material () specially adapted for touch screen, comprising a carrier layer () having a length and a width and a thickness () that is relatively small compared to said length and said width. The composite material also comprises a plurality of electrically conductive or semi-conductive particles (). The particles () are agglomerated to form a plurality of agglomerates () dispersed within the carrier layer such that each said agglomerate comprises a plurality of the particles (). The agglomerates are arranged to provide electrical conduction across the thickness of the carrier layer in response to applied pressure such that the electrically responsive composite material has a resistance that reduces in response to applied pressure.
