PCT No. PCT/DE92/00658 Sec. 371 Date Jun. 23, 1994 Sec. 102(e) Date Jun. 23, 1994 PCT Filed Aug. 6, 1992 PCT Pub. No. WO93/02739 PCT Pub. Date Feb. 18, 1993A stimulation electrode having a porous surface coating whose active surface area is significantly greater than the surface area defined by the geometric shape of the electrode, wherein the surface coating comprises an inert material, i.e. a material having no or only a very slight oxidation tendency, wherein the material of the surface coating is formed from an inert element, an inert chemical compound and/or an inert alloy, and the active surface area, by virtue of its fractal-like geometry, is greater by a factor of at least one thousand than the surface area defined by the basic geometric shape of the electrode.
