The invention relates to a system comprising a portable device for transmitting signals to a second device, wherein the portable device can be worn on the body of a user. The portable device comprises at least two electrodes and transmitter electronics for applying an electrical signal between the electrodes in such a manner that the signal can be coupled into the body of a user by means of the electrodes and can be detected by means of at least one electrode of the second device when emitted by the body. According to an embodiment of the invention, a portable device is characterized in that components of transmitter electronics and/or of an application different from transmitter electronics are interposed between the electrodes and/or that there is an air gap. |
