An electric stimulator for brain, heart, skin and internal organs in animals and plants where the electrodes are distributed on a supporting structure. The supporting structure may be adapted for brain, heart, skin or other internal organs, as for DBS, heart pacemaker, TENS, etc. The invention discloses a plurality of electrodes at the surface of the supporting structure, from which electrically stimulating currents can be injected into the organism. Turning off an electrode while turning on another electrode has the effect of moving the stimulation within the body of the organism from one point to another point, with the same effect but with less spent energy than physically moving the whole electrode support. We call this electrode shifting. Rotational and translational electrode shifting are possible. The invention also discloses random changes of the electrode shifting, and random changes of the stimulation time and of the stimulation duration.
