Abstract

A device for supplying electrical energy and/or supplying data to an electronic module, comprising a transmitting coil that has a coil axis and at least two energy receiving parts that are arranged side by side and have receiving coils, the coil axes of which run in the same direction or run parallel to the transmitting coil axis. Each of the coils is integrated in resonance circuits. The energy receiving parts supply electronics and, together with the same, are galvanically separated from one another by an insulating area of separation which is bridged by a data signal coupling line.
