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 (1501, 1502) to facilitate the conduction of electricity by quantum tunneling. Dielectric particles (1505, 1506) are added of a size relative to the acicular particles such that a plurality of these dielectric particles are dispersed between adjacent acicular particles.
