Abstract
This application generally relates to deformable elastomeric conductors and differential signaling transmission techniques. According to one embodiment, a deformable elastomeric conductor is configured to transmit electrical signals. It comprises: an elastomeric polymer matrix; and conductive filler material uniformly dispersed in the elastomeric polymer matrix sufficient to render the material electrically conductive. The conductive filler material may include substantially non-entangled particles having an aspect ratio sufficiently large to enable the particles to substantially remain in contact and/or in close proximity with adjacent particles so as to maintain conductive pathways in the material when the material is subjected to deformation up to and exceeding 10% strain. Thus, over a transmission distance of an electrical signal through the conductor, the transmission does not suffer greater than about 3 dB of signal attenuation when subjected to the deformation.
