Abstract
An interdigital electronic device comprises a conductor, an interdigital electrode, and a composite material disposed between the conductor and the interdigital electrode for electrically connecting the conductor and the interdigital electrode under application of sufficient pressure therebetween. The composite material comprises conductive particles at least partially embedded in an electrically insulating layer. The conductive particles have no relative orientation and are disposed so that substantially all electrical connections made between the conductor and the interdigital electrode are in the z direction. At least one of the conductor and the interdigital electrode is movable toward the other.
