ABSTRACT:
In order to excite living cells, a FM transmitter transmits for a period t at a frequency f such that the difference between f and a reference frequency f.sub.O sets the amplitude of a desired nerve stimulation pulse. A receiver implanted in the living body is inductively coupled to the transmitter and processes the signal so as to obtain an output signal having an amplitude which is proportional to the frequency deviation. The duration of the stimulation pulse is adjustable independently of the amplitude. The output signal is applied between two electrodes which are implanted in the vicinity of the cells to be excited and can be multiplexed to excite several pairs of electrodes in succession by an electronic circuit advanced by signal segments at a frequency at one end of the deviation range.
