ABSTRACT:
An interconnection system for transferring either electrical energy in the form of power and data signals or both is disclosed. Capacitive coupling devices are shown connected to a memory device such as an erasable programmable read only memory chip, in a form suitable for use in a smart data entry card. The capacitive coupling devices employ a dielectric medium having a relatively high dielectric constant due to the orientation of the crystals of the dielectric medium. Barium Titinate having a dielectric constant of 18,000 in the direction of the crystal axis is used. Only small bearing pressures sufficient to wipe contaminants from the exposed contact pads are required.
