Electronic device for transmitting data by inductive coupling and intracorporeal current

An electronic device comprising:

• a first device configured to transmit data by intracorporeal current, the first device including a first electrode configured to be capacitively coupled with a body of a user or capacitively coupled in an intracorporeal current conduction path of the electronic device;
• a circuit configured to electrically bias the first electrode, the circuit including an electric coil that is configured to, in response to an alternating-current (AC) signal, generate an alternating magnetic field having field lines incident on the first electrode, the field lines incident on the first electrode inducing a current in the first electrode, the current inducing an electric field that generates an intracorporeal current, the electric coil including coaxial windings around a magnetically conductive core, the electric coil having a magnetic axis parallel to a conduction plane of the first electrode, and
• a second device configured to transmit data by inductive coupling, wherein the electric coil is an antenna coil of the second device, the first device and the second device including a common AC signal generator configured to provide a first AC signal for data transmission by intracorporeal current and a second AC signal for data transmission by inductive coupling.
