Abstract
In a general aspect, an electronic device can include a device configured to transmit data by intracorporeal current. The device configured to transmit data by intracorporeal current can include 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. The electronic device can further include a circuit configured to electrically bias the first electrode. The circuit can include an electric coil arranged near the first electrode. The electric coil can be 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 can induce a current in the first electrode, where the current induces an electric field that generates an intracorporeal current.
