Abstract
An implantable device () is used to emit electrical stimulation signals to surrounding tissue by means of at least one stimulation electrode (). The device () has a sensor unit (), which generates a useful signal (D) in the form of analogue voltage pulses () from externally fed signals, and an output stage () which generates the stimulation signals (E) from the useful signal (D). The output stage () emits the stimulation signals (E) in, averaged over time, a substantially DC voltage free fashion to an external ground (), which can be connected to the tissue ().
