We developed stimulating and detecting electrodes. We experimentally examined three dimensional (3‐D) distributions of electric fields in living pig skin under and around the stimulating electrodes with the detecting electrodes and rectangular pulsed electrical current stimulation (RPECS). We verified our previous physical assumption, E ≈ I / (A σ dz ), in the skin under the electrode, where E, I, A and σ dz respectively represent the electric field, the externally imposed peak current, the cross sectional area of the stimulating electrode and the perpendicular conductivity of the skin. Pulses were 30 mA, 140 μs and 128 pulses per second (pps). These parameters were previously used in our laboratory to enhance cutaneous regeneration, in vivo, with RPECS. © 1996 Wiley‐Liss, Inc.
