An electrically conductive adhesive comprises electrically conductive particles mixed in a non-conductive base at such a mixing ratio that the conductive particles are not in contact with one another. When this adhesive is disposed between facing electrodes, it provides electric conductivity between...http://www.google.com/patents/US4113981?utm_source=gb-gplus-sharePatent US4113981 - Electrically conductive adhesive connecting arrays of conductors
