A new material has been developed consisting of metal particles intimately distributed in a polymer. This composite becomes a conductor under compression, tension or twisting, exhibiting a resistive range of one trillion to one, and following a smooth, repeatable curve. It has been shown that the conductivity arises from the quantum tunnelling effect. The material is used in a wide range of switches and sensors, as a replacement in standard components and also in novel applications.
