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.

Composite material

A polymer composition comprises at least one substantially non-conductive polymer binder and at least first and second electrically conductive fillers. The first electrically conductive filler is comprised of particles having avoid-bearing structure; and the second electrically conductive filler is comprised of particles which are acicular in shape.

Polymer composition

An electrically responsive composite material is disclosed, along with a method of producing an electrically responsive composite material, a transducer having a substrate for supporting a flowable polymer liquid and a method of fabricating a transducer. The electrically responsive composite material produced is configurable for application in a transducer. The method includes the steps of receiving the flowable polymer liquid and introducing electrically conductive acicular particles () to facilitate the conduction of electricity by quantum tunneling. Dielectric particles () are added of a size relative to the acicular particles such that a plurality of these dielectric particles are dispersed between adjacent acicular particles.
