ABSTRACT:
A device for electrically stimulating the skin in response to an electrical signal includes a flexible substrate on one surface of which is formed an electrically conductive pattern having a number of electrodes. Each of the electrodes is coated with a layer of a corrosion resistive material, such as titanium. An insulating layer extends over this surface of the substrate and has apertures therethrough aligned with the electrodes. A conductive ground plane layer is then applied over the insulating layer and also has apertures therethrough which are aligned with each of the electrodes. The stimulator is placed against the user so that the coated electrodes are in contact with the skin. In response to the received electrical signal, each electrode is sequentially stimulated by a negative and a positive electrical pulse. The negative and positive pulses have magnitudes which differ in a predetermined relationship so that the pH of the skin adjacent to the electrode is not altered substantially by the electrical stimulation.
