Patent ID: 8099023

Claim:
A bias-able device consisting essentially of: a conductive substrate; a rubber material disposed over the conductive substrate, wherein the rubber material comprises a plurality of nanotubes distributed throughout a rubber matrix to provide the rubber material with a mechanical conformability and an electrical resistivity of about 10 5 ohm-cm to about 10 10 ohm-cm and wherein the rubber matrix comprises one or more rubbers selected from the group consisting of ethylene-propylene-diene monomers (EPDM), epichiorohydrins, urethanes styrene-butadienes, silicons, nitrile rubbers, butyl rubbers, polyester thermoplastic rubbers, natural rubbers, and one or more biocompatible rubbers selected from the group consisting of polycarboxylic acids, polyvinylpyrrolidone, and cellulosic polymers, and wherein the plurality of nanotubes has a weight loading of about 0.1% or less throughout the rubber matrix; a surface material disposed over the rubber material; and a conductive foam disposed between the conductive substrate and the rubber material.
