Claim:
1. An electrically responsive composite material, comprising: a carrier layer having a length extending in a first direction and a width extending in a second direction and a thickness extending in a third direction, said thickness being relatively small compared to said length and said width; and a plurality of electrically conductive or semi-conductive particles, said particles being agglomerated to form a plurality of agglomerates dispersed within the carrier layer such that each said agglomerate comprises a plurality of said particles, wherein each said agglomerate has a first dimension in said third direction, that is equal to or longer than said thickness of said carrier layer, such that each said agglomerate by itself is arranged to provide a path of electrical conduction across the thickness of said carrier layer in response to applied pressure such that said electrically responsive composite material has a resistance that reduces in response to applied pressure.
