Abstract
An apparatus for communicating electrical power and data between downhole devices. The apparatus includes a wellbore tubular having a wall. An electrical device is positioned in a wellbore region to an exterior of the wellbore tubular. A first acoustic coupling element is positioned to the exterior of the wellbore tubular and is electrically connected to the electrical device. A second acoustic coupling element is positioned to an interior of the wellbore tubular. The second acoustic coupling element is operable to transmit electrical power to and receive data from the first acoustic coupling element through communication of acoustic signals through the wall of the wellbore tubular.
