Abstract:
1. A method of producing a composite material capable of transition to a resilient electrically responsive composite material for application in a transducer, in which the resilient electrically responsive material is configured to experience a change in an electrical property in response to exposure to a form of applied energy, said method comprising the steps of: receiving a flowable polymer liquid capable of transition into a resilient material; introducing electrically conductive acicular particles to said flowable polymer liquid to facilitate the conduction of electricity by quantum tunnelling; and adding dielectric particles to said flowable polymer liquid; and mixing said acicular particles and said dielectric particles within said flowable polymer liquid, wherein said acicular particles have a large dimension and a small dimension, said small dimension and the size of said dielectric particles being between 10 nanometers and 300 nanometers, a plurality of said dielectric particles are dispersed between adjacent acicular particles during said step of mixing, and said dielectric particles consisting of dielectric material only and being in a form that is separate from said electrically conductive acicular particles.
